Description

Functions and Procedures

function SDL_acos(x: cdouble): cdouble; cdecl; external SDL_LibName;

Calculate the arc cosine of x; that is, the value (in radians) whose cosine equals x. \since This function is available since SDL 2.0.4.

function SDL_acosf(x: cfloat): cfloat; cdecl; external SDL_LibName;

Calculate the arc cosine of x; that is, the value (in radians) whose cosine equals x. \since This function is available since SDL 2.0.8.

procedure SDL_AddEventWatch(filter: TSDL_EventFilter; userdata: Pointer) cdecl; external SDL_LibName;

Add a function which is called when an event is added to the queue.

procedure SDL_AddHintCallback(const name: PAnsiChar; callback: TSDL_HintCallback; userdata: Pointer); cdecl; external SDL_LibName;

function SDL_AddTimer(interval: cuint32; callback: TSDL_TimerCallback; param: Pointer): TSDL_TimerID; cdecl; external SDL_LibName;

Add a new timer to the pool of timers already running. A timer ID, or NULL when an error occurs.

function SDL_AllocFormat(pixel_format: cuint32): PSDL_PixelFormat; cdecl; external SDL_LibName;

Create an SDL_PixelFormat structure corresponding to a pixel format. Returned structure may come from a shared global cache (i.e. not newly allocated), and hence should not be modified, especially the palette. Weird errors such as `Blit combination not supported` may occur. \param pixel_format one of the SDL_PixelFormatEnum values \returns the new SDL_PixelFormat structure or NULL on failure; call SDL_GetError() for more information. \since This function is available since SDL 2.0.0. \sa SDL_FreeFormat

function SDL_AllocPalette(ncolors: cint): PSDL_Palette; cdecl; external SDL_LibName;

Create a palette structure with the specified number of color entries. The palette entries are initialized to white. \param ncolors represents the number of color entries in the color palette \returns a new SDL_Palette structure on success or NULL on failure (e.g. if there wasn't enough memory); call SDL_GetError() for more information. \since This function is available since SDL 2.0.0. \sa SDL_FreePalette

function SDL_AllocRW: PSDL_RWops; cdecl; external SDL_LibName;

RWFrom functions*

function SDL_AudioStreamAvailable(stream: PSDL_AudioStream): cint; cdecl; external SDL_LibName;

Get the number of converted/resampled bytes available.

Initialize an SDL_AudioCVT structure for conversion. Before an SDL_AudioCVT structure can be used to convert audio data it must be initialized with source and destination information. This function will zero out every field of the SDL_AudioCVT, so it must be called before the application fills in the final buffer information. Once this function has returned successfully, and reported that a conversion is necessary, the application fills in the rest of the fields in SDL_AudioCVT, now that it knows how large a buffer it needs to allocate, and then can call SDL_ConvertAudio() to complete the conversion. \param cvt an SDL_AudioCVT structure filled in with audio conversion information \param src_format the source format of the audio data; for more info see SDL_AudioFormat \param src_channels the number of channels in the source \param src_rate the frequency (sample-frames-per-second) of the source \param dst_format the destination format of the audio data; for more info see SDL_AudioFormat \param dst_channels the number of channels in the destination \param dst_rate the frequency (sample-frames-per-second) of the destination \returns 1 if the audio filter is prepared, 0 if no conversion is needed, or a negative error code on failure; call SDL_GetError() for more information. \since This function is available since SDL 2.0.0. \sa SDL_ConvertAudio

function SDL_CaptureMouse(enabled: TSDL_Bool): cint; cdecl; external SDL_LibName;

Capture the mouse and to track input outside an SDL window. Capturing enables your app to obtain mouse events globally, instead of just within your window. Not all video targets support this function. When capturing is enabled, the current window will get all mouse events, but unlike relative mode, no change is made to the cursor and it is not restrained to your window. This function may also deny mouse input to other windows–both those in your application and others on the system–so you should use this function sparingly, and in small bursts. For example, you might want to track the mouse while the user is dragging something, until the user releases a mouse button. It is not recommended that you capture the mouse for long periods of time, such as the entire time your app is running. For that, you should probably use SDL_SetRelativeMouseMode() or SDL_SetWindowGrab(), depending on your goals. While captured, mouse events still report coordinates relative to the current (foreground) window, but those coordinates may be outside the bounds of the window (including negative values). Capturing is only allowed for the foreground window. If the window loses focus while capturing, the capture will be disabled automatically. While capturing is enabled, the current window will have the `SDL_WINDOW_MOUSE_CAPTURE` flag set. Please note that as of SDL 2.0.22, SDL will attempt to "auto capture" the mouse while the user is pressing a button; this is to try and make mouse behavior more consistent between platforms, and deal with the common case of a user dragging the mouse outside of the window. This means that if you are calling SDL_CaptureMouse() only to deal with this situation, you no longer have to (although it is safe to do so). If this causes problems for your app, you can disable auto capture by setting the `SDL_HINT_MOUSE_AUTO_CAPTURE` hint to zero. \param enabled SDL_TRUE to enable capturing, SDL_FALSE to disable. \returns 0 on success or -1 if not supported; call SDL_GetError() for more information. \since This function is available since SDL 2.0.4. \sa SDL_GetGlobalMouseState

procedure SDL_ClearHints(); cdecl; external SDL_LibName;

Clear all hints. This function is automatically called during SDL_Quit(), and deletes all callbacks without calling them and frees all memory associated with hints. If you're calling this from application code you probably want to call SDL_ResetHints() instead. This function will be removed from the API the next time we rev the ABI. \since This function is available since SDL 2.0.0. \sa SDL_ResetHints

procedure SDL_ClearQueuedAudio(dev: TSDL_AudioDeviceID); cdecl; external SDL_LibName;

Drop any queued audio data waiting to be sent to the hardware. Immediately after this call, SDL_GetQueuedAudioSize() will return 0. For output devices, the hardware will start playing silence if more audio isn't queued. For capture devices, the hardware will start filling the empty queue with new data if the capture device isn't paused. This will not prevent playback of queued audio that's already been sent to the hardware, as we can not undo that, so expect there to be some fraction of a second of audio that might still be heard. This can be useful if you want to, say, drop any pending music or any unprocessed microphone input during a level change in your game. You may not queue or dequeue audio on a device that is using an application-supplied callback; calling this function on such a device always returns 0. You have to use the audio callback or queue audio, but not both. You should not call SDL_LockAudio() on the device before clearing the queue; SDL handles locking internally for this function. This function always succeeds and thus returns void. \param dev the device ID of which to clear the audio queue \since This function is available since SDL 2.0.4. \sa SDL_GetQueuedAudioSize \sa SDL_QueueAudio \sa SDL_DequeueAudio

procedure SDL_CloseAudio; cdecl; external SDL_LibName;

This function is a legacy means of closing the audio device. This function is equivalent to calling... ```c SDL_CloseAudioDevice(1); ``` ...and is only useful if you used the legacy SDL_OpenAudio() function. \since This function is available since SDL 2.0.0. \sa SDL_OpenAudio

procedure SDL_CloseAudioDevice(dev: TSDL_AudioDeviceID); cdecl; external SDL_LibName;

Use this function to shut down audio processing and close the audio device. The application should close open audio devices once they are no longer needed. Calling this function will wait until the device's audio callback is not running, release the audio hardware and then clean up internal state. No further audio will play from this device once this function returns. This function may block briefly while pending audio data is played by the hardware, so that applications don't drop the last buffer of data they supplied. The device ID is invalid as soon as the device is closed, and is eligible for reuse in a new SDL_OpenAudioDevice() call immediately. \param dev an audio device previously opened with SDL_OpenAudioDevice() \since This function is available since SDL 2.0.0. \sa SDL_OpenAudioDevice

function SDL_COMPILEDVERSION: Cardinal;

This is the version number macro for the current SDL version.

procedure SDL_CompilerBarrier();

The compiler barrier prevents the compiler from reordering reads and writes to globally visible variables across the call.

function SDL_CondSignal(cond: PSDL_Cond): cint; cdecl; external SDL_LibName;

Restart one of the threads that are waiting on the condition variable. \param cond the condition variable to signal \returns 0 on success or a negative error code on failure; call SDL_GetError() for more information. \since This function is available since SDL 2.0.0.

function SDL_CondWait(cond: PSDL_Cond; mutex: PSDL_Mutex): cint; cdecl; external SDL_LibName;

Wait until a condition variable is signaled. This function unlocks the specified `mutex` and waits for another thread to call SDL_CondSignal() or SDL_CondBroadcast() on the condition variable `cond`. Once the condition variable is signaled, the mutex is re-locked and the function returns. The mutex must be locked before calling this function. This function is the equivalent of calling SDL_CondWaitTimeout() with a time length of SDL_MUTEX_MAXWAIT. \param cond the condition variable to wait on \param mutex the mutex used to coordinate thread access \returns 0 when it is signaled or a negative error code on failure; call SDL_GetError() for more information. \since This function is available since SDL 2.0.0.

function SDL_CondWaitTimeout(cond: PSDL_Cond; mutex: PSDL_Mutex; ms: cuint32): cint; cdecl; external SDL_LibName;

Wait until a condition variable is signaled or a certain time has passed. This function unlocks the specified `mutex` and waits for another thread to call SDL_CondSignal() or SDL_CondBroadcast() on the condition variable `cond`, or for the specified time to elapse. Once the condition variable is signaled or the time elapsed, the mutex is re-locked and the function returns. The mutex must be locked before calling this function. \param cond the condition variable to wait on \param mutex the mutex used to coordinate thread access \param ms the maximum time to wait, in milliseconds, or SDL_MUTEX_MAXWAIT to wait indefinitely \returns 0 if the condition variable is signaled, SDL_MUTEX_TIMEDOUT if the condition is not signaled in the allotted time, or a negative error code on failure; call SDL_GetError() for more information. \since This function is available since SDL 2.0.0.

function SDL_ConvertAudio(cvt: PSDL_AudioCVT): cint; cdecl; external SDL_LibName;

Convert audio data to a desired audio format. This function does the actual audio data conversion, after the application has called SDL_BuildAudioCVT() to prepare the conversion information and then filled in the buffer details. Once the application has initialized the `cvt` structure using SDL_BuildAudioCVT(), allocated an audio buffer and filled it with audio data in the source format, this function will convert the buffer, in-place, to the desired format. The data conversion may go through several passes; any given pass may possibly temporarily increase the size of the data. For example, SDL might expand 16-bit data to 32 bits before resampling to a lower frequency, shrinking the data size after having grown it briefly. Since the supplied buffer will be both the source and destination, converting as necessary in-place, the application must allocate a buffer that will fully contain the data during its largest conversion pass. After SDL_BuildAudioCVT() returns, the application should set the `cvt->len` field to the size, in bytes, of the source data, and allocate a buffer that is `cvt->len * cvt->len_mult` bytes long for the `buf` field. The source data should be copied into this buffer before the call to SDL_ConvertAudio(). Upon successful return, this buffer will contain the converted audio, and `cvt->len_cvt` will be the size of the converted data, in bytes. Any bytes in the buffer past `cvt->len_cvt` are undefined once this function returns. \param cvt an SDL_AudioCVT structure that was previously set up by SDL_BuildAudioCVT(). \returns 0 if the conversion was completed successfully or a negative error code on failure; call SDL_GetError() for more information. \since This function is available since SDL 2.0.0. \sa SDL_BuildAudioCVT

function SDL_ConvertSurface(src: PSDL_Surface; const fmt: PSDL_PixelFormat; flags: cuint32): PSDL_Surface; cdecl; external SDL_LibName;

Creates a new surface of the specified format, and then copies and maps the given surface to it so the blit of the converted surface will be as fast as possible. If this function fails, it returns NULL. The flags parameter is passed to SDL_CreateRGBSurface() and has those semantics. You can also pass SDL_RLEACCEL in the flags parameter and SDL will try to RLE accelerate colorkey and alpha blits in the resulting surface.

function SDL_CreateCursor( const data: pcuint8; const mask: pcuint8; w: cint; h: cint; hot_x: cint; hot_y: cint): PSDL_Cursor; cdecl; external SDL_LibName;

Create a cursor using the specified bitmap data and mask (in MSB format). `mask` has to be in MSB (Most Significant Bit) format. The cursor width (`w`) must be a multiple of 8 bits. The cursor is created in black and white according to the following: - data=0, mask=1: white - data=1, mask=1: black - data=0, mask=0: transparent - data=1, mask=0: inverted color if possible, black if not. Cursors created with this function must be freed with SDL_FreeCursor(). If you want to have a color cursor, or create your cursor from an SDL_Surface, you should use SDL_CreateColorCursor(). Alternately, you can hide the cursor and draw your own as part of your game's rendering, but it will be bound to the framerate. Also, since SDL 2.0.0, SDL_CreateSystemCursor() is available, which provides twelve readily available system cursors to pick from. \param data the color value for each pixel of the cursor \param mask the mask value for each pixel of the cursor \param w the width of the cursor \param h the height of the cursor \param hot_x the X-axis location of the upper left corner of the cursor relative to the actual mouse position \param hot_y the Y-axis location of the upper left corner of the cursor relative to the actual mouse position \returns a new cursor with the specified parameters on success or NULL on failure; call SDL_GetError() for more information. \since This function is available since SDL 2.0.0. \sa SDL_FreeCursor \sa SDL_SetCursor \sa SDL_ShowCursor

function SDL_CreateMutex: PSDL_Mutex; cdecl; external SDL_LibName;

function SDL_CreateThread(fn: TSDL_ThreadFunction; name: PAnsiChar; data: Pointer): PSDL_Thread; cdecl; external SDL_LibName;

Create a thread. Thread naming is a little complicated: Most systems have very small limits for the string length (BeOS has 32 bytes, Linux currently has 16, Visual C++ 6.0 has nine!), and possibly other arbitrary rules. You'll have to see what happens with your system's debugger. The name should be UTF-8 (but using the naming limits of C identifiers is a better bet). There are no requirements for thread naming conventions, so long as the string is null-terminated UTF-8, but these guidelines are helpful in choosing a name: http://stackoverflow.com/questions/149932/naming-conventions-for-threads If a system imposes requirements, SDL will try to munge the string for it (truncate, etc), but the original string contents will be available from SDL_GetThreadName().

\brief Create a window with the specified position, dimensions, and flags. \param title The title of the window, in UTF-8 encoding. \param x The x position of the window, ::SDL_WINDOWPOS_CENTERED, or ::SDL_WINDOWPOS_UNDEFINED. \param y The y position of the window, ::SDL_WINDOWPOS_CENTERED, or ::SDL_WINDOWPOS_UNDEFINED. \param w The width of the window, in screen coordinates. \param h The height of the window, in screen coordinates. \param flags The flags for the window, a mask of any of the following: ::SDL_WINDOW_FULLSCREEN, ::SDL_WINDOW_OPENGL, ::SDL_WINDOW_HIDDEN, ::SDL_WINDOW_BORDERLESS, ::SDL_WINDOW_RESIZABLE, ::SDL_WINDOW_MAXIMIZED, ::SDL_WINDOW_MINIMIZED, ::SDL_WINDOW_INPUT_GRABBED, ::SDL_WINDOW_ALLOW_HIGHDPI, ::SDL_WINDOW_VULKAN. \return The created window, or NULL if window creation failed. If the window is created with the SDL_WINDOW_ALLOW_HIGHDPI flag, its size in pixels may differ from its size in screen coordinates on platforms with high-DPI support (e.g. iOS and Mac OS X). Use SDL_GetWindowSize() to query the client area's size in screen coordinates, and SDL_GL_GetDrawableSize(), SDL_Vulkan_GetDrawableSize(), or SDL_GetRendererOutputSize() to query the drawable size in pixels. If the window is created with any of the SDL_WINDOW_OPENGL or SDL_WINDOW_VULKAN flags, then the corresponding LoadLibrary function (SDL_GL_LoadLibrary or SDL_Vulkan_LoadLibrary) is called and the corresponding UnloadLibrary function is called by SDL_DestroyWindow(). If SDL_WINDOW_VULKAN is specified and there isn't a working Vulkan driver, SDL_CreateWindow() will fail because SDL_Vulkan_LoadLibrary() will fail. \note On non-Apple devices, SDL requires you to either not link to the Vulkan loader or link to a dynamic library version. This limitation may be removed in a future version of SDL. \sa SDL_DestroyWindow() \sa SDL_GL_LoadLibrary() \sa SDL_Vulkan_LoadLibrary()

function SDL_DequeueAudio(dev: TSDL_AudioDeviceID; data: Pointer; len: cuint32): cuint32; cdecl; external SDL_LibName;

Dequeue more audio on non-callback devices. If you are looking to queue audio for output on a non-callback playback device, you want SDL_QueueAudio() instead. SDL_DequeueAudio() will always return 0 if you use it with playback devices. SDL offers two ways to retrieve audio from a capture device: you can either supply a callback that SDL triggers with some frequency as the device records more audio data, (push method), or you can supply no callback, and then SDL will expect you to retrieve data at regular intervals (pull method) with this function. There are no limits on the amount of data you can queue, short of exhaustion of address space. Data from the device will keep queuing as necessary without further intervention from you. This means you will eventually run out of memory if you aren't routinely dequeueing data. Capture devices will not queue data when paused; if you are expecting to not need captured audio for some length of time, use SDL_PauseAudioDevice() to stop the capture device from queueing more data. This can be useful during, say, level loading times. When unpaused, capture devices will start queueing data from that point, having flushed any capturable data available while paused. This function is thread-safe, but dequeueing from the same device from two threads at once does not promise which thread will dequeue data first. You may not dequeue audio from a device that is using an application-supplied callback; doing so returns an error. You have to use the audio callback, or dequeue audio with this function, but not both. You should not call SDL_LockAudio() on the device before dequeueing; SDL handles locking internally for this function. \param dev the device ID from which we will dequeue audio \param data a pointer into where audio data should be copied \param len the number of bytes (not samples!) to which (data) points \returns the number of bytes dequeued, which could be less than requested; call SDL_GetError() for more information. \since This function is available since SDL 2.0.5. \sa SDL_ClearQueuedAudio \sa SDL_GetQueuedAudioSize

procedure SDL_DetachThread(thread:TSDL_Thread); cdecl; external SDL_LibName;

A thread may be "detached" to signify that it should not remain until another thread has called SDL_WaitThread() on it. Detaching a thread is useful for long-running threads that nothing needs to synchronize with or further manage. When a detached thread is done, it simply goes away. There is no way to recover the return code of a detached thread. If you need this, don't detach the thread and instead use SDL_WaitThread(). Once a thread is detached, you should usually assume the SDL_Thread isn't safe to reference again, as it will become invalid immediately upon the detached thread's exit, instead of remaining until someone has called SDL_WaitThread() to finally clean it up. As such, don't detach the same thread more than once. If a thread has already exited when passed to SDL_DetachThread(), it will stop waiting for a call to SDL_WaitThread() and clean up immediately. It is not safe to detach a thread that might be used with SDL_WaitThread(). You may not call SDL_WaitThread() on a thread that has been detached. Use either that function or this one, but not both, or behavior is undefined. It is safe to pass NIL to this function; it is a no-op.

function SDL_GetAudioDeviceName(index: cint; iscapture: cint): PAnsiChar; cdecl; external SDL_LibName;

Get the human-readable name of a specific audio device. This function is only valid after successfully initializing the audio subsystem. The values returned by this function reflect the latest call to SDL_GetNumAudioDevices(); re-call that function to redetect available hardware. The string returned by this function is UTF-8 encoded, read-only, and managed internally. You are not to free it. If you need to keep the string for any length of time, you should make your own copy of it, as it will be invalid next time any of several other SDL functions are called. \param index the index of the audio device; valid values range from 0 to SDL_GetNumAudioDevices() - 1 \param iscapture non-zero to query the list of recording devices, zero to query the list of output devices. \returns the name of the audio device at the requested index, or NULL on error. \since This function is available since SDL 2.0.0. \sa SDL_GetNumAudioDevices \sa SDL_GetDefaultAudioInfo

function SDL_GetAudioDeviceSpec(index: cint; iscapture: cint; spec: PSDL_AudioSpec): cint; cdecl; external SDL_LibName;

Get the preferred audio format of a specific audio device. This function is only valid after a successfully initializing the audio subsystem. The values returned by this function reflect the latest call to SDL_GetNumAudioDevices(); re-call that function to redetect available hardware. `spec` will be filled with the sample rate, sample format, and channel count. \param index the index of the audio device; valid values range from 0 to SDL_GetNumAudioDevices() - 1 \param iscapture non-zero to query the list of recording devices, zero to query the list of output devices. \param spec The SDL_AudioSpec to be initialized by this function. \returns 0 on success, nonzero on error \since This function is available since SDL 2.0.16. \sa SDL_GetNumAudioDevices \sa SDL_GetDefaultAudioInfo

function SDL_GetAudioDeviceStatus(dev: TSDL_AudioDeviceID): TSDL_AudioStatus; cdecl; external SDL_LibName;

Use this function to get the current audio state of an audio device. \param dev the ID of an audio device previously opened with SDL_OpenAudioDevice() \returns the SDL_AudioStatus of the specified audio device. \since This function is available since SDL 2.0.0. \sa SDL_PauseAudioDevice

function SDL_GetAudioDriver(index: cint): PAnsiChar; cdecl; external SDL_LibName;

Use this function to get the name of a built in audio driver. The list of audio drivers is given in the order that they are normally initialized by default; the drivers that seem more reasonable to choose first (as far as the SDL developers believe) are earlier in the list. The names of drivers are all simple, low-ASCII identifiers, like "alsa", "coreaudio" or "xaudio2". These never have Unicode characters, and are not meant to be proper names. \param index the index of the audio driver; the value ranges from 0 to SDL_GetNumAudioDrivers() - 1 \returns the name of the audio driver at the requested index, or NULL if an invalid index was specified. \since This function is available since SDL 2.0.0. \sa SDL_GetNumAudioDrivers

function SDL_GetAudioStatus: TSDL_AudioStatus; cdecl; external SDL_LibName;

This function is a legacy means of querying the audio device. New programs might want to use SDL_GetAudioDeviceStatus() instead. This function is equivalent to calling... ```c SDL_GetAudioDeviceStatus(1); ``` ...and is only useful if you used the legacy SDL_OpenAudio() function. \returns the SDL_AudioStatus of the audio device opened by SDL_OpenAudio(). \since This function is available since SDL 2.0.0. \sa SDL_GetAudioDeviceStatus

function SDL_GetBasePath(): PAnsiChar; cdecl; external SDL_LibName;

Get the directory where the application was run from. This is not necessarily a fast call, so you should call this once near startup and save the string if you need it. **Mac OS X and iOS Specific Functionality**: If the application is in a ".app" bundle, this function returns the Resource directory (e.g. MyApp.app/Contents/Resources/). This behaviour can be overridden by adding a property to the Info.plist file. Adding a string key with the name SDL_FILESYSTEM_BASE_DIR_TYPE with a supported value will change the behaviour. Supported values for the SDL_FILESYSTEM_BASE_DIR_TYPE property (Given an application in /Applications/SDLApp/MyApp.app): - `resource`: bundle resource directory (the default). For example: `/Applications/SDLApp/MyApp.app/Contents/Resources` - `bundle`: the Bundle directory. For example: `/Applications/SDLApp/MyApp.app/` - `parent`: the containing directory of the bundle. For example: `/Applications/SDLApp/` The returned path is guaranteed to end with a path separator ('\' on Windows, '/' on most other platforms). The pointer returned is owned by the caller. Please call SDL_free() on the pointer when done with it. \returns an absolute path in UTF-8 encoding to the application data directory. nil will be returned on error or when the platform doesn't implement this functionality, call SDL_GetError() for more information. \since This function is available since SDL 2.0.1. \sa SDL_GetPrefPath

function SDL_GetClipboardText(): PAnsiChar; cdecl; external SDL_LibName;

Get UTF-8 text from the clipboard, which must be freed with SDL_free(). This functions returns empty string if there was not enough memory left for a copy of the clipboard's content. \returns the clipboard text on success or an empty string on failure; call SDL_GetError() for more information. Caller must call SDL_free() on the returned pointer when done with it (even if there was an error). \since This function is available since SDL 2.0.0. \sa SDL_HasClipboardText \sa SDL_SetClipboardText

procedure SDL_GetClipRect(surface: PSDL_Surface; rect: PSDL_Rect); cdecl; external SDL_LibName;

Gets the clipping rectangle for the destination surface in a blit. rect must be a pointer to a valid rectangle which will be filled with the correct values.

function SDL_GetClosestDisplayMode(displayIndex: cint; const mode: PSDL_DisplayMode; closest: PSDL_DisplayMode): PSDL_DisplayMode; cdecl; external SDL_LibName;

Get the closest match to the requested display mode. mode The desired display mode closest A pointer to a display mode to be filled in with the closest match of the available display modes. The passed in value closest, or nil if no matching video mode was available. The available display modes are scanned, and closest is filled in with the closest mode matching the requested mode and returned. The mode format and refresh_rate default to the desktop mode if they are 0. The modes are scanned with size being first priority, format being second priority, and finally checking the refresh_rate. If all the available modes are too small, then nil is returned. SDL_GetNumDisplayModes() SDL_GetDisplayMode()

function SDL_GetColorKey(surface: PSDL_Surface; key: pcuint32): cint; cdecl; external SDL_LibName;

Gets the color key (transparent pixel) in a blittable surface. surface The surface to update key A pointer filled in with the transparent pixel in the native surface format 0 on success, or -1 if the surface is not valid or colorkey is not enabled.

This function returns the L1 cache line size of the CPU. This is useful for determining multi-threaded structure padding or SIMD prefetch sizes.

function SDL_GetCPUCount(): cint; cdecl; external SDL_LibName;

This function returns the number of CPU cores available.

function SDL_GetCurrentAudioDriver: PAnsiChar; cdecl; external SDL_LibName;

Get the name of the current audio driver. The returned string points to internal static memory and thus never becomes invalid, even if you quit the audio subsystem and initialize a new driver (although such a case would return a different static string from another call to this function, of course). As such, you should not modify or free the returned string. \returns the name of the current audio driver or NULL if no driver has been initialized. \since This function is available since SDL 2.0.0. \sa SDL_AudioInit

function SDL_GetCurrentDisplayMode(displayIndex: cint; mode: PSDL_DisplayMode): cint; cdecl; external SDL_LibName;

Get the active cursor. This function returns a pointer to the current cursor which is owned by the library. It is not necessary to free the cursor with SDL_FreeCursor(). \returns the active cursor or NULL if there is no mouse. \since This function is available since SDL 2.0.0. \sa SDL_SetCursor

function SDL_GetDefaultAudioInfo(name: PPAnsiChar; spec: PSDL_AudioSpec; iscapture: cint): cint; cdecl; external SDL_LibName;

Get the name and preferred format of the default audio device. Some (but not all!) platforms have an isolated mechanism to get information about the "default" device. This can actually be a completely different device that's not in the list you get from SDL_GetAudioDeviceSpec(). It can even be a network address! (This is discussed in SDL_OpenAudioDevice().) As a result, this call is not guaranteed to be performant, as it can query the sound server directly every time, unlike the other query functions. You should call this function sparingly! `spec` will be filled with the sample rate, sample format, and channel count, if a default device exists on the system. If `name` is provided, will be filled with either a dynamically-allocated UTF-8 string or nil. \param name A pointer to be filled with the name of the default device (can be nil). Please call SDL_free() when you are done with this pointer! \param spec The SDL_AudioSpec to be initialized by this function. \param iscapture non-zero to query the default recording device, zero to query the default output device. \returns 0 on success, nonzero on error \since This function is available since SDL 2.24.0. \sa SDL_GetAudioDeviceName \sa SDL_GetAudioDeviceSpec \sa SDL_OpenAudioDevice

function SDL_GetDefaultCursor: PSDL_Cursor; cdecl; external SDL_LibName;

Get the default cursor. \returns the default cursor on success or NULL on failure. \since This function is available since SDL 2.0.0. \sa SDL_CreateSystemCursor

function SDL_GetDisplayBounds(displayIndex: cint; rect: PSDL_Rect): cint; cdecl; external SDL_LibName;

Get the desktop area represented by a display, with the primary display located at 0,0 0 on success, or -1 if the index is out of range. SDL_GetNumVideoDisplays()

function SDL_GetDisplayDPI(displayIndex: cint; ddpi, hdpi, vdpi: pcfloat): cint; cdecl; external SDL_LibName;

\brief Get the dots/pixels-per-inch for a display \note Diagonal, horizontal and vertical DPI can all be optionally returned if the parameter is non-NULL. \return 0 on success, or -1 if no DPI information is available or the index is out of range. \sa SDL_GetNumVideoDisplays()

function SDL_GetDisplayMode(displayIndex: cint; modeIndex: cint; mode: PSDL_DisplayMode): cint; cdecl; external SDL_LibName;

Fill in information about a specific display mode. The display modes are sorted in this priority: bits per pixel -> more colors to fewer colors width -> largest to smallest height -> largest to smallest refresh rate -> highest to lowest SDL_GetNumDisplayModes()

function SDL_GetDisplayName(displayIndex: cint): PAnsiChar; cdecl; external SDL_LibName;

Get the name of a display in UTF-8 encoding The name of a display, or nil for an invalid display index. SDL_GetNumVideoDisplays()

function SDL_GetDisplayOrientation(displayIndex: cint): TSDL_DisplayOrientation; cdecl; external SDL_LibName;

\brief Get the orientation of a display \return The orientation of the display, or SDL_ORIENTATION_UNKNOWN if it isn't available. \sa SDL_GetNumVideoDisplays()

function SDL_GetDisplayUsableBounds(displayIndex: cint; rect: PSDL_Rect): cint; cdecl; external SDL_LibName;

\brief Get the usable desktop area represented by a display, with the primary display located at 0,0 This is the same area as SDL_GetDisplayBounds() reports, but with portions reserved by the system removed. For example, on Mac OS X, this subtracts the area occupied by the menu bar and dock. Setting a window to be fullscreen generally bypasses these unusable areas, so these are good guidelines for the maximum space available to a non-fullscreen window. \return 0 on success, or -1 if the index is out of range. \sa SDL_GetDisplayBounds() \sa SDL_GetNumVideoDisplays()

function SDL_GetError: PAnsiChar; cdecl; external SDL_LibName;

\brief Get the last error message that was set SDL API functions may set error messages and then succeed, so you should only use the error value if a function fails. This returns a pointer to a static buffer for convenience and should not be called by multiple threads simultaneously. \return a pointer to the last error message that was set

function SDL_GetErrorMsg(const errstr: PAnsiChar; maxlen: cint): PAnsiChar; cdecl; external SDL_LibName;

\brief Get the last error message that was set for the current thread SDL API functions may set error messages and then succeed, so you should only use the error value if a function fails. \param errstr A buffer to fill with the last error message that was set for the current thread \param maxlen The size of the buffer pointed to by the errstr parameter \return errstr

function SDL_GetEventFilter(var filter: PSDL_EventFilter; var userdata: PPointer): TSDL_Bool cdecl; external SDL_LibName;

Return the current event filter - can be used to "chain" filters. If there is no event filter set, this function returns SDL_FALSE.

function SDL_GetEventState(type_: TSDL_EventType): cuint8;

function SDL_GetGlobalMouseState(x, y: pcint32): cuint32; cdecl; external SDL_LibName;

Get the current state of the mouse in relation to the desktop. This works similarly to SDL_GetMouseState(), but the coordinates will be reported relative to the top-left of the desktop. This can be useful if you need to track the mouse outside of a specific window and SDL_CaptureMouse() doesn't fit your needs. For example, it could be useful if you need to track the mouse while dragging a window, where coordinates relative to a window might not be in sync at all times. Note: SDL_GetMouseState() returns the mouse position as SDL understands it from the last pump of the event queue. This function, however, queries the OS for the current mouse position, and as such, might be a slightly less efficient function. Unless you know what you're doing and have a good reason to use this function, you probably want SDL_GetMouseState() instead. \param x filled in with the current X coord relative to the desktop; can be NULL \param y filled in with the current Y coord relative to the desktop; can be NULL \returns the current button state as a bitmask which can be tested using the SDL_BUTTON(X) macros. \since This function is available since SDL 2.0.4. \sa SDL_CaptureMouse

function SDL_GetGrabbedWindow(): PSDL_Window; cdecl; external SDL_LibName;

\brief Get the window that currently has an input grab enabled. \return This returns the window if input is grabbed, and NULL otherwise. \sa SDL_SetWindowGrab()

function SDL_GetKeyboardFocus: PSDL_Window; cdecl; external SDL_LibName;

Query the window which currently has keyboard focus. \returns the window with keyboard focus. \since This function is available since SDL 2.0.0.

function SDL_GetKeyboardState(numkeys: pcint): pcuint8; cdecl; external SDL_LibName;

Get a snapshot of the current state of the keyboard. The pointer returned is a pointer to an internal SDL array. It will be valid for the whole lifetime of the application and should not be freed by the caller. A array element with a value of 1 means that the key is pressed and a value of 0 means that it is not. Indexes into this array are obtained by using SDL_Scancode values. Use SDL_PumpEvents() to update the state array. This function gives you the current state after all events have been processed, so if a key or button has been pressed and released before you process events, then the pressed state will never show up in the SDL_GetKeyboardState() calls. Note: This function doesn't take into account whether shift has been pressed or not. \param numkeys if non-nil, receives the length of the returned array \returns a pointer to an array of key states. \since This function is available since SDL 2.0.0. \sa SDL_PumpEvents \sa SDL_ResetKeyboard

function SDL_GetKeyFromName(name: PAnsiChar): TSDL_Keycode; cdecl; external SDL_LibName;

Get a key code from a human-readable name. \param name the human-readable key name \returns key code, or `SDLK_UNKNOWN` if the name wasn't recognized; call SDL_GetError() for more information. \since This function is available since SDL 2.0.0. \sa SDL_GetKeyFromScancode \sa SDL_GetKeyName \sa SDL_GetScancodeFromName

function SDL_GetKeyFromScancode(scancode: TSDL_Scancode): TSDL_Keycode; cdecl; external SDL_LibName;

Get the key code corresponding to the given scancode according to the current keyboard layout. See SDL_Keycode for details. \param scancode the desired SDL_Scancode to query \returns the SDL_Keycode that corresponds to the given SDL_Scancode. \since This function is available since SDL 2.0.0. \sa SDL_GetKeyName \sa SDL_GetScancodeFromKey

function SDL_GetKeyName(key: TSDL_Keycode): PAnsiChar; cdecl; external SDL_LibName;

Get a human-readable name for a key. See SDL_Scancode and SDL_Keycode for details. \param key the desired SDL_Keycode to query \returns a pointer to a UTF-8 string that stays valid at least until the next call to this function. If you need it around any longer, you must copy it. If the key doesn't have a name, this function returns an empty string (""). \since This function is available since SDL 2.0.0. \sa SDL_GetKeyFromName \sa SDL_GetKeyFromScancode \sa SDL_GetScancodeFromKey

procedure SDL_GetMemoryFunctions( malloc_func: PSDL_malloc_func; calloc_func: PSDL_calloc_func; realloc_func: PSDL_realloc_func; free_func: PSDL_free_func ); cdecl; external SDL_LibName;

Get the current set of SDL memory functions \since This function is available since SDL 2.0.7.

function SDL_GetModState: TSDL_Keymod; cdecl; external SDL_LibName;

Get the current key modifier state for the keyboard. \returns an OR'd combination of the modifier keys for the keyboard. See SDL_Keymod for details. \since This function is available since SDL 2.0.0. \sa SDL_GetKeyboardState \sa SDL_SetModState

function SDL_GetMouseFocus: PSDL_Window; cdecl; external SDL_LibName;

Get the window which currently has mouse focus. \returns the window with mouse focus. \since This function is available since SDL 2.0.0.

function SDL_GetMouseState(x: pcint; y: pcint): cuint32; cdecl; external SDL_LibName;

Retrieve the current state of the mouse. The current button state is returned as a button bitmask, which can be tested using the `SDL_BUTTON(X)` macros (where `X` is generally 1 for the left, 2 for middle, 3 for the right button), and `x` and `y` are set to the mouse cursor position relative to the focus window. You can pass NULL for either `x` or `y`. \param x the x coordinate of the mouse cursor position relative to the focus window \param y the y coordinate of the mouse cursor position relative to the focus window \returns a 32-bit button bitmask of the current button state. \since This function is available since SDL 2.0.0. \sa SDL_GetGlobalMouseState \sa SDL_GetRelativeMouseState \sa SDL_PumpEvents

function SDL_GetNumAllocations(): cint; cdecl; external SDL_LibName;

Get the number of outstanding (unfreed) allocations \since This function is available since SDL 2.0.7.

function SDL_GetNumAudioDevices(iscapture: cint): cint; cdecl; external SDL_LibName;

Get the number of built-in audio devices. This function is only valid after successfully initializing the audio subsystem. Note that audio capture support is not implemented as of SDL 2.0.4, so the `iscapture` parameter is for future expansion and should always be zero for now. This function will return -1 if an explicit list of devices can't be determined. Returning -1 is not an error. For example, if SDL is set up to talk to a remote audio server, it can't list every one available on the Internet, but it will still allow a specific host to be specified in SDL_OpenAudioDevice(). In many common cases, when this function returns a value <= 0, it can still successfully open the default device (NULL for first argument of SDL_OpenAudioDevice()). This function may trigger a complete redetect of available hardware. It should not be called for each iteration of a loop, but rather once at the start of a loop: ```c // Don't do this: for (int i = 0; i < SDL_GetNumAudioDevices(0); i++) // do this instead: const int count = SDL_GetNumAudioDevices(0); for (int i = 0; i < count; ++i) do_something_here(); ``` \param iscapture zero to request playback devices, non-zero to request recording devices \returns the number of available devices exposed by the current driver or -1 if an explicit list of devices can't be determined. A return value of -1 does not necessarily mean an error condition. \since This function is available since SDL 2.0.0. \sa SDL_GetAudioDeviceName \sa SDL_OpenAudioDevice

function SDL_GetNumAudioDrivers: cint; cdecl; external SDL_LibName;

Use this function to get the number of built-in audio drivers. This function returns a hardcoded number. This never returns a negative value; if there are no drivers compiled into this build of SDL, this function returns zero. The presence of a driver in this list does not mean it will function, it just means SDL is capable of interacting with that interface. For example, a build of SDL might have esound support, but if there's no esound server available, SDL's esound driver would fail if used. By default, SDL tries all drivers, in its preferred order, until one is found to be usable. \returns the number of built-in audio drivers. \since This function is available since SDL 2.0.0. \sa SDL_GetAudioDriver

function SDL_GetNumDisplayModes(displayIndex: cint): cint; cdecl; external SDL_LibName;

Returns the number of available display modes. SDL_GetDisplayMode()

function SDL_GetNumRenderDrivers: cint32 cdecl; external SDL_LibName;

Get the number of 2D rendering drivers available for the current display. A render driver is a set of code that handles rendering and texture management on a particular display. Normally there is only one, but some drivers may have several available with different capabilities. SDL_GetRenderDriverInfo() SDL_CreateRenderer()

Get the human readable name of a pixel format. \param format the pixel format to query \returns the human readable name of the specified pixel format or `SDL_PIXELFORMAT_UNKNOWN` if the format isn't recognized. \since This function is available since SDL 2.0.0.

function SDL_GetPlatform: PAnsiChar; cdecl; external SDL_LibName;

Gets the name of the platform.

function SDL_GetPointDisplayIndex(const point: PSDL_Point): cint; cdecl; external SDL_LibName;

Get the index of the display containing a point \param point the point to query \returns the index of the display containing the point or a negative error code on failure; call SDL_GetError() for more information. \since This function is available since SDL 2.24.0. \sa SDL_GetDisplayBounds \sa SDL_GetNumVideoDisplays

function SDL_GetPowerInfo(secs: pcint; pct: pcint): TSDL_PowerState; cdecl; external SDL_LibName;

\brief Get the current power supply details. \param secs Seconds of battery life left. You can pass a NULL here if you don't care. Will return -1 if we can't determine a value, or we're not running on a battery. \param pct Percentage of battery life left, between 0 and 100. You can pass a NULL here if you don't care. Will return -1 if we can't determine a value, or we're not running on a battery. \return The state of the battery (if any).

function SDL_GetPreferredLocales(): PSDL_Locale; cdecl; external SDL_LibName;

\brief Report the user's preferred locale. This returns an array of SDL_Locale structs, the final item zeroed out. When the caller is done with this array, it should call SDL_free() on the returned value; all the memory involved is allocated in a single block, so a single SDL_free() will suffice. Returned language strings are in the format xx, where 'xx' is an ISO-639 language specifier (such as 'en' for English, 'de' for German, etc). Country strings are in the format YY, where 'YY' is an ISO-3166 country code (such as "US" for the United States, 'CA' for Canada, etc). Country might be NULL if there's no specific guidance on them (so you might get ( 'en', 'US' ) for American English, but ( 'en', NIL ) means "English language, generically"). Language strings are never NIL, except to terminate the array. Please note that not all of these strings are 2 characters; some are three or more. The returned list of locales are in the order of the user's preference. For example, a German citizen that is fluent in US English and knows enough Japanese to navigate around Tokyo might have a list like: [ 'de', 'en_US', 'jp', NIL ]. Someone from England might prefer British English (where "color" is spelled "colour", etc), but will settle for anything like it: [ 'en_GB', 'en', NIL ]. This function returns NIL on error, including when the platform does not supply this information at all. This might be a "slow" call that has to query the operating system. It's best to ask for this once and save the results. However, this list can change, usually because the user has changed a system preference outside of your program; SDL will send an SDL_LOCALECHANGED event in this case, if possible, and you can call this function again to get an updated copy of preferred locales. \return array of locales, terminated with a locale with a NIL language field. Will return NIL on error.

function SDL_GetPrefPath(org: PAnsiChar; app: PAnsiChar): PAnsiChar; cdecl; external SDL_LibName;

Get the user-and-app-specific path where files can be written. Get the "pref dir". This is meant to be where users can write personal files (preferences and save games, etc) that are specific to your application. This directory is unique per user, per application. This function will decide the appropriate location in the native filesystem, create the directory if necessary, and return a string of the absolute path to the directory in UTF-8 encoding. On Windows, the string might look like: `C:\\Users\\bob\\AppData\\Roaming\\My Company\\My Program Name\\` On Linux, the string might look like: `/home/bob/.local/share/My Program Name/` On Mac OS X, the string might look like: `/Users/bob/Library/Application Support/My Program Name/` You should assume the path returned by this function is the only safe place to write files (and that SDL_GetBasePath(), while it might be writable, or even the parent of the returned path, isn't where you should be writing things). Both the org and app strings may become part of a directory name, so please follow these rules: - Try to use the same org string (_including case-sensitivity_) for all your applications that use this function. - Always use a unique app string for each one, and make sure it never changes for an app once you've decided on it. - Unicode characters are legal, as long as it's UTF-8 encoded, but... - ...only use letters, numbers, and spaces. Avoid punctuation like "Game Name 2: Bad Guy's Revenge!" ... "Game Name 2" is sufficient. The returned path is guaranteed to end with a path separator ('\' on Windows, '/' on most other platforms). The pointer returned is owned by the caller. Please call SDL_free() on the pointer when done with it. \param org the name of your organization \param app the name of your application \returns a UTF-8 string of the user directory in platform-dependent notation. nil if there's a problem (creating directory failed, etc.). \since This function is available since SDL 2.0.1. \sa SDL_GetBasePath

function SDL_GetPrimarySelectionText(): PAnsiChar; cdecl; external SDL_LibName;

Get UTF-8 text from the primary selection, which must be freed with SDL_free(). This functions returns empty string if there was not enough memory left for a copy of the primary selection's content. \returns the primary selection text on success or an empty string on failure; call SDL_GetError() for more information. Caller must call SDL_free() on the returned pointer when done with it (even if there was an error). \since This function is available since SDL 2.26.1. \sa SDL_HasPrimarySelectionText \sa SDL_SetPrimarySelectionText

function SDL_GetQueuedAudioSize(dev: TSDL_AudioDeviceID): cuint32; cdecl; external SDL_LibName;

Get the number of bytes of still-queued audio. For playback devices: this is the number of bytes that have been queued for playback with SDL_QueueAudio(), but have not yet been sent to the hardware. Once we've sent it to the hardware, this function can not decide the exact byte boundary of what has been played. It's possible that we just gave the hardware several kilobytes right before you called this function, but it hasn't played any of it yet, or maybe half of it, etc. For capture devices, this is the number of bytes that have been captured by the device and are waiting for you to dequeue. This number may grow at any time, so this only informs of the lower-bound of available data. You may not queue or dequeue audio on a device that is using an application-supplied callback; calling this function on such a device always returns 0. You have to use the audio callback or queue audio, but not both. You should not call SDL_LockAudio() on the device before querying; SDL handles locking internally for this function. \param dev the device ID of which we will query queued audio size \returns the number of bytes (not samples!) of queued audio. \since This function is available since SDL 2.0.4. \sa SDL_ClearQueuedAudio \sa SDL_QueueAudio \sa SDL_DequeueAudio

function SDL_GetScancodeName(scancode: TSDL_Scancode): PAnsiChar; cdecl; external SDL_LibName;

Get a human-readable name for a scancode. See SDL_Scancode for details. **Warning**: The returned name is by design not stable across platforms, e.g. the name for `SDL_SCANCODE_LGUI` is "Left GUI" under Linux but "Left Windows" under Microsoft Windows, and some scancodes like `SDL_SCANCODE_NONUSBACKSLASH` don't have any name at all. There are even scancodes that share names, e.g. `SDL_SCANCODE_RETURN` and `SDL_SCANCODE_RETURN2` (both called "Return"). This function is therefore unsuitable for creating a stable cross-platform two-way mapping between strings and scancodes. \param scancode the desired SDL_Scancode to query \returns a pointer to the name for the scancode.

function SDL_LoadFunction(handle: Pointer; name: PAnsiChar): Pointer; cdecl; external SDL_LibName;

Look up the address of the named function in a shared object. This function pointer is no longer valid after calling SDL_UnloadObject(). This function can only look up C function names. Other languages may have name mangling and intrinsic language support that varies from compiler to compiler. Make sure you declare your function pointers with the same calling convention as the actual library function. Your code will crash mysteriously if you do not do this. If the requested function doesn't exist, nil is returned. \param handle a valid shared object handle returned by SDL_LoadObject() \param name the name of the function to look up \returns a pointer to the function or nil if there was an error; call SDL_GetError() for more information. \since This function is available since SDL 2.0.0. \sa SDL_LoadObject \sa SDL_UnloadObject

function SDL_LoadWAV(file_: PAnsiChar; spec: PSDL_AudioSpec; audio_buf: ppcuint8; audio_len: pcuint32): PSDL_AudioSpec;

Loads a WAV from a file. Compatibility convenience function.

function SDL_LoadWAV_RW(src: PSDL_RWops; freesrc: cint; spec: PSDL_AudioSpec; audio_buf: ppcuint8; audio_len: pcuint32): PSDL_AudioSpec; cdecl; external SDL_LibName;

Load the audio data of a WAVE file into memory. Loading a WAVE file requires `src`, `spec`, `audio_buf` and `audio_len` to be valid pointers. The entire data portion of the file is then loaded into memory and decoded if necessary. If `freesrc` is non-zero, the data source gets automatically closed and freed before the function returns. Supported formats are RIFF WAVE files with the formats PCM (8, 16, 24, and 32 bits), IEEE Float (32 bits), Microsoft ADPCM and IMA ADPCM (4 bits), and A-law and mu-law (8 bits). Other formats are currently unsupported and cause an error. If this function succeeds, the pointer returned by it is equal to `spec` and the pointer to the audio data allocated by the function is written to `audio_buf` and its length in bytes to `audio_len`. The SDL_AudioSpec members `freq`, `channels`, and `format` are set to the values of the audio data in the buffer. The `samples` member is set to a sane default and all others are set to zero. It's necessary to use SDL_FreeWAV() to free the audio data returned in `audio_buf` when it is no longer used. Because of the underspecification of the .WAV format, there are many problematic files in the wild that cause issues with strict decoders. To provide compatibility with these files, this decoder is lenient in regards to the truncation of the file, the fact chunk, and the size of the RIFF chunk. The hints `SDL_HINT_WAVE_RIFF_CHUNK_SIZE`, `SDL_HINT_WAVE_TRUNCATION`, and `SDL_HINT_WAVE_FACT_CHUNK` can be used to tune the behavior of the loading process. Any file that is invalid (due to truncation, corruption, or wrong values in the headers), too big, or unsupported causes an error. Additionally, any critical I/O error from the data source will terminate the loading process with an error. The function returns NULL on error and in all cases (with the exception of `src` being NULL), an appropriate error message will be set. It is required that the data source supports seeking. Example: ```c SDL_LoadWAV_RW(SDL_RWFromFile("sample.wav", "rb"), 1, &spec, &buf, &len); ``` Note that the SDL_LoadWAV macro does this same thing for you, but in a less messy way: ```c SDL_LoadWAV("sample.wav", &spec, &buf, &len); ``` \param src The data source for the WAVE data \param freesrc If non-zero, SDL will _always_ free the data source \param spec An SDL_AudioSpec that will be filled in with the wave file's format details \param audio_buf A pointer filled with the audio data, allocated by the function. \param audio_len A pointer filled with the length of the audio data buffer in bytes \returns This function, if successfully called, returns `spec`, which will be filled with the audio data format of the wave source data. `audio_buf` will be filled with a pointer to an allocated buffer containing the audio data, and `audio_len` is filled with the length of that audio buffer in bytes. This function returns NULL if the .WAV file cannot be opened, uses an unknown data format, or is corrupt; call SDL_GetError() for more information. When the application is done with the data returned in `audio_buf`, it should call SDL_FreeWAV() to dispose of it. \since This function is available since SDL 2.0.0. \sa SDL_FreeWAV \sa SDL_LoadWAV

procedure SDL_LockAudio; cdecl; external SDL_LibName;

This function is a legacy means of locking the audio device. New programs might want to use SDL_LockAudioDevice() instead. This function is equivalent to calling... ```c SDL_LockAudioDevice(1); ``` ...and is only useful if you used the legacy SDL_OpenAudio() function. \since This function is available since SDL 2.0.0. \sa SDL_LockAudioDevice \sa SDL_UnlockAudio \sa SDL_UnlockAudioDevice

procedure SDL_LockAudioDevice(dev: TSDL_AudioDeviceID); cdecl; external SDL_LibName;

Use this function to lock out the audio callback function for a specified device. The lock manipulated by these functions protects the audio callback function specified in SDL_OpenAudioDevice(). During a SDL_LockAudioDevice()/SDL_UnlockAudioDevice() pair, you can be guaranteed that the callback function for that device is not running, even if the device is not paused. While a device is locked, any other unpaused, unlocked devices may still run their callbacks. Calling this function from inside your audio callback is unnecessary. SDL obtains this lock before calling your function, and releases it when the function returns. You should not hold the lock longer than absolutely necessary. If you hold it too long, you'll experience dropouts in your audio playback. Ideally, your application locks the device, sets a few variables and unlocks again. Do not do heavy work while holding the lock for a device. It is safe to lock the audio device multiple times, as long as you unlock it an equivalent number of times. The callback will not run until the device has been unlocked completely in this way. If your application fails to unlock the device appropriately, your callback will never run, you might hear repeating bursts of audio, and SDL_CloseAudioDevice() will probably deadlock. Internally, the audio device lock is a mutex; if you lock from two threads at once, not only will you block the audio callback, you'll block the other thread. \param dev the ID of the device to be locked \since This function is available since SDL 2.0.0. \sa SDL_UnlockAudioDevice

procedure SDL_LockJoysticks(); cdecl; external SDL_LibName;

Locking for multi-threaded access to the joystick API If you are using the joystick API or handling events from multiple threads you should use these locking functions to protect access to the joysticks. In particular, you are guaranteed that the joystick list won't change, so the API functions that take a joystick index will be valid, and joystick and game controller events will not be delivered. As of SDL 2.26.0, you can take the joystick lock around reinitializing the joystick subsystem, to prevent other threads from seeing joysticks in an uninitialized state. However, all open joysticks will be closed and SDL functions called with them will fail. \since This function is available since SDL 2.0.7.

function SDL_LockMutex(mutex: PSDL_Mutex): cint; cdecl; external SDL_LibName;

Lock the mutex. This will block until the mutex is available, which is to say it is in the unlocked state and the OS has chosen the caller as the next thread to lock it. Of all threads waiting to lock the mutex, only one may do so at a time. It is legal for the owning thread to lock an already-locked mutex. It must unlock it the same number of times before it is actually made available for other threads in the system (this is known as a "recursive mutex"). \param mutex the mutex to lock \return 0, or -1 on error. \since This function is available since SDL 2.0.0.

procedure SDL_LockSensors(); cdecl; external SDL_LibName;

Locking for multi-threaded access to the sensor API If you are using the sensor API or handling events from multiple threads you should use these locking functions to protect access to the sensors. In particular, you are guaranteed that the sensor list won't change, so the API functions that take a sensor index will be valid, and sensor events will not be delivered. \since This function is available since SDL 2.0.14.

function SDL_LockSurface(surface: PSDL_Surface): cint; cdecl; external SDL_LibName;

Sets up a surface for directly accessing the pixels. Between calls to SDL_LockSurface() / SDL_UnlockSurface(), you can write to and read from surface.pixels, using the pixel format stored in surface.format. Once you are done accessing the surface, you should use SDL_UnlockSurface() to release it. Not all surfaces require locking. If SDL_MUSTLOCK(surface) evaluates to 0, then you can read and write to the surface at any time, and the pixel format of the surface will not change. No operating system or library calls should be made between lock/unlock pairs, as critical system locks may be held during this time. SDL_LockSurface() returns 0, or -1 if the surface couldn't be locked. SDL_UnlockSurface()

function SDL_LockTexture(texture: PSDL_Texture; const rect: PSDL_Rect; pixels: PPointer; pitch: pcint): cint; cdecl; external SDL_LibName;

Lock a portion of the texture for write-only pixel access. texture The texture to lock for access, which was created with SDL_TEXTUREACCESS_STREAMING. rect A pointer to the rectangle to lock for access. If the rect is NULL, the entire texture will be locked. pixels This is filled in with a pointer to the locked pixels, appropriately offset by the locked area. pitch This is filled in with the pitch of the locked pixels. 0 on success, or -1 if the texture is not valid or was not created with ::SDL_TEXTUREACCESS_STREAMING. SDL_UnlockTexture()

function SDL_LockTextureToSurface(texture: PSDL_Texture; const rect: PSDL_Rect; surface: PPSDL_Surface): cint; cdecl; external SDL_LibName;

\brief Lock a portion of the texture for write-only pixel access. Expose it as a SDL surface. \param texture The texture to lock for access, which was created with ::SDL_TEXTUREACCESS_STREAMING. \param rect A pointer to the rectangle to lock for access.

Map an RGB triple to an opaque pixel value for a given pixel format. This function maps the RGB color value to the specified pixel format and returns the pixel value best approximating the given RGB color value for the given pixel format. If the format has a palette (8-bit) the index of the closest matching color in the palette will be returned. If the specified pixel format has an alpha component it will be returned as all 1 bits (fully opaque).

This function maps the RGBA color value to the specified pixel format and returns the pixel value best approximating the given RGBA color value for the given pixel format. If the specified pixel format has no alpha component the alpha value will be ignored (as it will be in formats with a palette). If the format has a palette (8-bit) the index of the closest matching color in the palette will be returned.

procedure SDL_MixAudio(dst: pcuint8; src: pcuint8; len: cuint32; volume: cint); cdecl; external SDL_LibName;

This function is a legacy means of mixing audio. This function is equivalent to calling... ```c SDL_MixAudioFormat(dst, src, format, len, volume); ``` ...where `format` is the obtained format of the audio device from the legacy SDL_OpenAudio() function. \param dst the destination for the mixed audio \param src the source audio buffer to be mixed \param len the length of the audio buffer in bytes \param volume ranges from 0 - 128, and should be set to SDL_MIX_MAXVOLUME for full audio volume \since This function is available since SDL 2.0.0. \sa SDL_MixAudioFormat

procedure SDL_MixAudioFormat(dst: pcuint8; src: pcuint8; format: TSDL_AudioFormat; len: cuint32; volume: cint); cdecl; external SDL_LibName;

Mix audio data in a specified format. This takes an audio buffer `src` of `len` bytes of `format` data and mixes it into `dst`, performing addition, volume adjustment, and overflow clipping. The buffer pointed to by `dst` must also be `len` bytes of `format` data. This is provided for convenience – you can mix your own audio data. Do not use this function for mixing together more than two streams of sample data. The output from repeated application of this function may be distorted by clipping, because there is no accumulator with greater range than the input (not to mention this being an inefficient way of doing it). It is a common misconception that this function is required to write audio data to an output stream in an audio callback. While you can do that, SDL_MixAudioFormat() is really only needed when you're mixing a single audio stream with a volume adjustment. \param dst the destination for the mixed audio \param src the source audio buffer to be mixed \param format the SDL_AudioFormat structure representing the desired audio format \param len the length of the audio buffer in bytes \param volume ranges from 0 - 128, and should be set to SDL_MIX_MAXVOLUME for full audio volume \since This function is available since SDL 2.0.0.

function SDL_OpenAudio(desired: PSDL_AudioSpec; obtained: PSDL_AudioSpec): cint; cdecl; external SDL_LibName;

This function is a legacy means of opening the audio device. This function remains for compatibility with SDL 1.2, but also because it's slightly easier to use than the new functions in SDL 2.0. The new, more powerful, and preferred way to do this is SDL_OpenAudioDevice(). This function is roughly equivalent to: ```c SDL_OpenAudioDevice(NULL, 0, desired, obtained, SDL_AUDIO_ALLOW_ANY_CHANGE); ``` With two notable exceptions: - If `obtained` is NULL, we use `desired` (and allow no changes), which means desired will be modified to have the correct values for silence, etc, and SDL will convert any differences between your app's specific request and the hardware behind the scenes. - The return value is always success or failure, and not a device ID, which means you can only have one device open at a time with this function. \param desired an SDL_AudioSpec structure representing the desired output format. Please refer to the SDL_OpenAudioDevice documentation for details on how to prepare this structure. \param obtained an SDL_AudioSpec structure filled in with the actual parameters, or NULL. \returns 0 if successful, placing the actual hardware parameters in the structure pointed to by `obtained`. If `obtained` is NULL, the audio data passed to the callback function will be guaranteed to be in the requested format, and will be automatically converted to the actual hardware audio format if necessary. If `obtained` is NULL, `desired` will have fields modified. This function returns a negative error code on failure to open the audio device or failure to set up the audio thread; call SDL_GetError() for more information. \since This function is available since SDL 2.0.0. \sa SDL_CloseAudio \sa SDL_LockAudio \sa SDL_PauseAudio \sa SDL_UnlockAudio

function SDL_OpenAudioDevice(device: PAnsiChar; iscapture: cint; desired: PSDL_AudioSpec; obtained: PSDL_AudioSpec; allowed_changes: cint): TSDL_AudioDeviceID; cdecl; external SDL_LibName;

Open a specific audio device. SDL_OpenAudio(), unlike this function, always acts on device ID 1. As such, this function will never return a 1 so as not to conflict with the legacy function. Please note that SDL 2.0 before 2.0.5 did not support recording; as such, this function would fail if `iscapture` was not zero. Starting with SDL 2.0.5, recording is implemented and this value can be non-zero. Passing in a `device` name of NULL requests the most reasonable default (and is equivalent to what SDL_OpenAudio() does to choose a device). The `device` name is a UTF-8 string reported by SDL_GetAudioDeviceName(), but some drivers allow arbitrary and driver-specific strings, such as a hostname/IP address for a remote audio server, or a filename in the diskaudio driver. An opened audio device starts out paused, and should be enabled for playing by calling SDL_PauseAudioDevice(devid, 0) when you are ready for your audio callback function to be called. Since the audio driver may modify the requested size of the audio buffer, you should allocate any local mixing buffers after you open the audio device. The audio callback runs in a separate thread in most cases; you can prevent race conditions between your callback and other threads without fully pausing playback with SDL_LockAudioDevice(). For more information about the callback, see SDL_AudioSpec. Managing the audio spec via 'desired' and 'obtained': When filling in the desired audio spec structure: - `desired->freq` should be the frequency in sample-frames-per-second (Hz). - `desired->format` should be the audio format (`AUDIO_S16SYS`, etc). - `desired->samples` is the desired size of the audio buffer, in _sample frames_ (with stereo output, two samples–left and right–would make a single sample frame). This number should be a power of two, and may be adjusted by the audio driver to a value more suitable for the hardware. Good values seem to range between 512 and 8096 inclusive, depending on the application and CPU speed. Smaller values reduce latency, but can lead to underflow if the application is doing heavy processing and cannot fill the audio buffer in time. Note that the number of sample frames is directly related to time by the following formula: `ms = (sampleframes*1000)/freq` - `desired->size` is the size in _bytes_ of the audio buffer, and is calculated by SDL_OpenAudioDevice(). You don't initialize this. - `desired->silence` is the value used to set the buffer to silence, and is calculated by SDL_OpenAudioDevice(). You don't initialize this. - `desired->callback` should be set to a function that will be called when the audio device is ready for more data. It is passed a pointer to the audio buffer, and the length in bytes of the audio buffer. This function usually runs in a separate thread, and so you should protect data structures that it accesses by calling SDL_LockAudioDevice() and SDL_UnlockAudioDevice() in your code. Alternately, you may pass a NULL pointer here, and call SDL_QueueAudio() with some frequency, to queue more audio samples to be played (or for capture devices, call SDL_DequeueAudio() with some frequency, to obtain audio samples). - `desired->userdata` is passed as the first parameter to your callback function. If you passed a NULL callback, this value is ignored. `allowed_changes` can have the following flags OR'd together: - `SDL_AUDIO_ALLOW_FREQUENCY_CHANGE` - `SDL_AUDIO_ALLOW_FORMAT_CHANGE` - `SDL_AUDIO_ALLOW_CHANNELS_CHANGE` - `SDL_AUDIO_ALLOW_SAMPLES_CHANGE` - `SDL_AUDIO_ALLOW_ANY_CHANGE` These flags specify how SDL should behave when a device cannot offer a specific feature. If the application requests a feature that the hardware doesn't offer, SDL will always try to get the closest equivalent. For example, if you ask for float32 audio format, but the sound card only supports int16, SDL will set the hardware to int16. If you had set SDL_AUDIO_ALLOW_FORMAT_CHANGE, SDL will change the format in the `obtained` structure. If that flag was *not* set, SDL will prepare to convert your callback's float32 audio to int16 before feeding it to the hardware and will keep the originally requested format in the `obtained` structure. The resulting audio specs, varying depending on hardware and on what changes were allowed, will then be written back to `obtained`. If your application can only handle one specific data format, pass a zero for `allowed_changes` and let SDL transparently handle any differences. \param device a UTF-8 string reported by SDL_GetAudioDeviceName() or a driver-specific name as appropriate. NULL requests the most reasonable default device. \param iscapture non-zero to specify a device should be opened for recording, not playback \param desired an SDL_AudioSpec structure representing the desired output format; see SDL_OpenAudio() for more information \param obtained an SDL_AudioSpec structure filled in with the actual output format; see SDL_OpenAudio() for more information \param allowed_changes 0, or one or more flags OR'd together \returns a valid device ID that is > 0 on success or 0 on failure; call SDL_GetError() for more information. For compatibility with SDL 1.2, this will never return 1, since SDL reserves that ID for the legacy SDL_OpenAudio() function. \since This function is available since SDL 2.0.0. \sa SDL_CloseAudioDevice \sa SDL_GetAudioDeviceName \sa SDL_LockAudioDevice \sa SDL_OpenAudio \sa SDL_PauseAudioDevice \sa SDL_UnlockAudioDevice

function SDL_OpenURL(const url: PAnsiChar): cint; cdecl; external SDL_LibName;

\brief Open an URL / URI in the browser or other Open a URL in a separate, system-provided application. How this works will vary wildly depending on the platform. This will likely launch what makes sense to handle a specific URL's protocol (a web browser for http://, etc), but it might also be able to launch file managers for directories and other things. What happens when you open a URL varies wildly as well: your game window may lose focus (and may or may not lose focus if your game was fullscreen or grabbing input at the time). On mobile devices, your app will likely move to the background or your process might be paused. Any given platform may or may not handle a given URL. If this is unimplemented (or simply unavailable) for a platform, this will fail with an error. A successful result does not mean the URL loaded, just that we launched something to handle it (or at least believe we did). All this to say: this function can be useful, but you should definitely test it on every platform you target. \param url A valid URL to open. \return 0 on success, or -1 on error.

procedure SDL_PauseAudio(pause_on: cint); cdecl; external SDL_LibName;

This function is a legacy means of pausing the audio device. New programs might want to use SDL_PauseAudioDevice() instead. This function is equivalent to calling... ```c SDL_PauseAudioDevice(1, pause_on); ``` ...and is only useful if you used the legacy SDL_OpenAudio() function. \param pause_on non-zero to pause, 0 to unpause \since This function is available since SDL 2.0.0. \sa SDL_GetAudioStatus \sa SDL_PauseAudioDevice

procedure SDL_PauseAudioDevice(dev: TSDL_AudioDeviceID; pause_on: cint); cdecl; external SDL_LibName;

Use this function to pause and unpause audio playback on a specified device. This function pauses and unpauses the audio callback processing for a given device. Newly-opened audio devices start in the paused state, so you must call this function with **pause_on**=0 after opening the specified audio device to start playing sound. This allows you to safely initialize data for your callback function after opening the audio device. Silence will be written to the audio device while paused, and the audio callback is guaranteed to not be called. Pausing one device does not prevent other unpaused devices from running their callbacks. Pausing state does not stack; even if you pause a device several times, a single unpause will start the device playing again, and vice versa. This is different from how SDL_LockAudioDevice() works. If you just need to protect a few variables from race conditions vs your callback, you shouldn't pause the audio device, as it will lead to dropouts in the audio playback. Instead, you should use SDL_LockAudioDevice(). \param dev a device opened by SDL_OpenAudioDevice() \param pause_on non-zero to pause, 0 to unpause \since This function is available since SDL 2.0.0. \sa SDL_LockAudioDevice

function SDL_PeepEvents(events: PSDL_Event; numevents: cint32; action: TSDL_EventAction; minType, maxType: TSDL_EventType): cint32 cdecl; external SDL_LibName;

Checks the event queue for messages and optionally returns them. If action is SDL_ADDEVENT, up to numevents events will be added to the back of the event queue. If action is SDL_PEEKEVENT, up to numevents events at the front of the event queue, within the specified minimum and maximum type, will be returned and will not be removed from the queue. If action is SDL_GETEVENT, up to numevents events at the front of the event queue, within the specified minimum and maximum type, will be returned and will be removed from the queue. Result: The number of events actually stored, or -1 if there was an error. This function is thread-safe.

function SDL_PIXELFLAG(X: cuint32): cuint32;

SDL2-for-Pascal: The SDL_DEFINE_PIXELFORMAT macro returns the underlying pixel format based on five arguments. The original C macro: #define SDL_DEFINE_PIXELFORMAT(type, order, layout, bits, bytes) \ ((1 << 28) | ((type) << 24) | ((order) << 20) | ((layout) << 16) | \ ((bits) << 8) | ((bytes) << 0)) This C implementation could be replaced by a Pascal function, but from a performance stand point this will be slower. Therefore we decided to keep it as it has been implemented before by the original binding authors and translate every pixel format constant by the very same expression: SDL_PIXELFORMAT_[...] = (1 shl 28) or (SDL_PIXELTYPE_[...] shl 24) or (SDL_BITMAPORDER_[...] shl 20) or ([...] shl 16) or ([...] shl 8) or ([...] shl 0); In the future it may be desirable to have a Pascal function. The prototype could look like this: function SDL_DEFINE_PIXELFORMAT(type, order, layour, bit, bytes: cuint32): Result;

function SDL_PixelFormatEnumToMasks(format: cuint32; bpp: pcint; Rmask: pcuint32; Gmask: pcuint32; Bmask: pcuint32; Amask: pcuint32): TSDL_Bool; cdecl; external SDL_LibName;

Convert one of the enumerated pixel formats to a bpp value and RGBA masks. \param format one of the SDL_PixelFormatEnum values \param bpp a bits per pixel value; usually 15, 16, or 32 \param Rmask a pointer filled in with the red mask for the format \param Gmask a pointer filled in with the green mask for the format \param Bmask a pointer filled in with the blue mask for the format \param Amask a pointer filled in with the alpha mask for the format \returns SDL_TRUE on success or SDL_FALSE if the conversion wasn't possible; call SDL_GetError() for more information. \since This function is available since SDL 2.0.0. \sa SDL_MasksToPixelFormatEnum

The actual format may differ, but pixel transfers will use this format. access A pointer filled in with the actual access to the texture. w A pointer filled in with the width of the texture in pixels. h A pointer filled in with the height of the texture in pixels. 0 on success, or -1 if the texture is not valid.

function SDL_QueueAudio(dev: TSDL_AudioDeviceID; data: Pointer; len: cuint32): cint; cdecl; external SDL_LibName;

Queue more audio on non-callback devices. If you are looking to retrieve queued audio from a non-callback capture device, you want SDL_DequeueAudio() instead. SDL_QueueAudio() will return -1 to signify an error if you use it with capture devices. SDL offers two ways to feed audio to the device: you can either supply a callback that SDL triggers with some frequency to obtain more audio (pull method), or you can supply no callback, and then SDL will expect you to supply data at regular intervals (push method) with this function. There are no limits on the amount of data you can queue, short of exhaustion of address space. Queued data will drain to the device as necessary without further intervention from you. If the device needs audio but there is not enough queued, it will play silence to make up the difference. This means you will have skips in your audio playback if you aren't routinely queueing sufficient data. This function copies the supplied data, so you are safe to free it when the function returns. This function is thread-safe, but queueing to the same device from two threads at once does not promise which buffer will be queued first. You may not queue audio on a device that is using an application-supplied callback; doing so returns an error. You have to use the audio callback or queue audio with this function, but not both. You should not call SDL_LockAudio() on the device before queueing; SDL handles locking internally for this function. Note that SDL2 does not support planar audio. You will need to resample from planar audio formats into a non-planar one (see SDL_AudioFormat) before queuing audio. \param dev the device ID to which we will queue audio \param data the data to queue to the device for later playback \param len the number of bytes (not samples!) to which `data` points \returns 0 on success or a negative error code on failure; call SDL_GetError() for more information. \since This function is available since SDL 2.0.4. \sa SDL_ClearQueuedAudio \sa SDL_GetQueuedAudioSize

function SDL_RenderFlush(renderer: PSDL_Renderer): cint; cdecl; external SDL_LibName;

Force the rendering context to flush any pending commands to the underlying rendering API. You do not need to (and in fact, shouldn't) call this function unless you are planning to call into OpenGL/Direct3D/Metal/whatever directly in addition to using an SDL_Renderer. This is for a very-specific case: if you are using SDL's render API, you asked for a specific renderer backend (OpenGL, Direct3D, etc), you set SDL_HINT_RENDER_BATCHING to "1", and you plan to make OpenGL/D3D/whatever calls in addition to SDL render API calls. If all of this applies, you should call SDL_RenderFlush() between calls to SDL's render API and the low-level API you're using in cooperation. In all other cases, you can ignore this function. This is only here to get maximum performance out of a specific situation. In all other cases, SDL will do the right thing, perhaps at a performance loss. This function is first available in SDL 2.0.10, and is not needed in 2.0.9 and earlier, as earlier versions did not queue rendering commands at all, instead flushing them to the OS immediately.

Be very careful of what you do in the event filter function, as it may run in a different thread! There is one caveat when dealing with the SDL_QUITEVENT event type. The event filter is only called when the window manager desires to close the application window. If the event filter returns 1, then the window will be closed, otherwise the window will remain open if possible. If the quit event is generated by an interrupt signal, it will bypass the internal queue and be delivered to the application at the next event poll.

function SDL_SetWindowHitTest(window: PSDL_Window; callback: TSDL_HitTest; callback_data: Pointer): cint; cdecl; external SDL_LibName;

\brief Provide a callback that decides if a window region has special properties. Normally windows are dragged and resized by decorations provided by the system window manager (a title bar, borders, etc), but for some apps, it makes sense to drag them from somewhere else inside the window itself; for example, one might have a borderless window that wants to be draggable from any part, or simulate its own title bar, etc. This function lets the app provide a callback that designates pieces of a given window as special. This callback is run during event processing if we need to tell the OS to treat a region of the window specially; the use of this callback is known as "hit testing." Mouse input may not be delivered to your application if it is within a special area; the OS will often apply that input to moving the window or resizing the window and not deliver it to the application. Specifying NULL for a callback disables hit-testing. Hit-testing is disabled by default. Platforms that don't support this functionality will return -1 unconditionally, even if you're attempting to disable hit-testing. Your callback may fire at any time, and its firing does not indicate any specific behavior (for example, on Windows, this certainly might fire when the OS is deciding whether to drag your window, but it fires for lots of other reasons, too, some unrelated to anything you probably care about _and when the mouse isn't actually at the location it is testing_). Since this can fire at any time, you should try to keep your callback efficient, devoid of allocations, etc. \param window The window to set hit-testing on. \param callback The callback to call when doing a hit-test. \param callback_data An app-defined void pointer passed to the callback. \return 0 on success, -1 on error (including unsupported).

procedure SDL_SetWindowKeyboardGrab(window: PSDL_Window; grabbed: TSDL_Bool); cdecl; external SDL_LibName;

Set a window's keyboard grab mode. Keyboard grab enables capture of system keyboard shortcuts like Alt+Tab or the Meta/Super key. Note that not all system keyboard shortcuts can be captured by applications (one example is Ctrl+Alt+Del on Windows). This is primarily intended for specialized applications such as VNC clients or VM frontends. Normal games should not use keyboard grab. When keyboard grab is enabled, SDL will continue to handle Alt+Tab when the window is full-screen to ensure the user is not trapped in your application. If you have a custom keyboard shortcut to exit fullscreen mode, you may suppress this behavior with `SDL_HINT_ALLOW_ALT_TAB_WHILE_GRABBED`. If the caller enables a grab while another window is currently grabbed, the other window loses its grab in favor of the caller's window. \param window The window for which the keyboard grab mode should be set. \param grabbed This is SDL_TRUE to grab keyboard, and SDL_FALSE to release. \since This function is available since SDL 2.0.16. \sa SDL_GetWindowKeyboardGrab \sa SDL_SetWindowMouseGrab \sa SDL_SetWindowGrab

Show a window. SDL_HideWindow()

function SDL_SIMDAlloc(const len: csize_t): Pointer; cdecl; external SDL_LibName;

Allocate memory in a SIMD-friendly way. This will allocate a block of memory that is suitable for use with SIMD instructions. Specifically, it will be properly aligned and padded for the system's supported vector instructions. The memory returned will be padded such that it is safe to read or write an incomplete vector at the end of the memory block. This can be useful so you don't have to drop back to a scalar fallback at the end of your SIMD processing loop to deal with the final elements without overflowing the allocated buffer. You must free this memory with SDL_FreeSIMD(), not free() or SDL_free(). Note that SDL will only deal with SIMD instruction sets it is aware of; for example, SDL 2.0.8 knows that SSE wants 16-byte vectors (SDL_HasSSE()), and AVX2 wants 32 bytes (SDL_HasAVX2()), but doesn't know that AVX-512 wants 64. To be clear: if you can't decide to use an instruction set with an SDL_Has*() function, don't use that instruction set with memory allocated through here. SDL_AllocSIMD(0) will return a non-NULL pointer, assuming the system isn't out of memory, but you are not allowed to dereference it (because you only own zero bytes of that buffer).

procedure SDL_SIMDFree(mem: Pointer); cdecl; external SDL_LibName;

Deallocate memory obtained from SDL_SIMDAlloc. It is not valid to use this function on a pointer from anything but SDL_SIMDAlloc() or SDL_SIMDRealloc(). It can't be used on pointers from SDL_malloc, GetMem, etc. However, SDL_SIMDFree(NIL) is a legal no-op. The memory pointed to by `mem` is no longer valid for access upon return, and may be returned to the system or reused by a future allocation. The pointer passed to this function is no longer safe to dereference once this function returns, and should be discarded.

function SDL_SIMDGetAlignment(): csize_t; cdecl; external SDL_LibName;

Report the alignment this system needs for SIMD allocations. This will return the minimum number of bytes to which a pointer must be aligned to be compatible with SIMD instructions on the current machine. For example, if the machine supports SSE only, it will return 16, but if it supports AVX-512F, it'll return 64 (etc). This only reports values for instruction sets SDL knows about, so if your SDL build doesn't have SDL_HasAVX512F(), then it might return 16 for the SSE support it sees and not 64 for the AVX-512 instructions that exist but SDL doesn't know about. Plan accordingly.

function SDL_SIMDRealloc(mem: Pointer; const len: csize_t): Pointer; cdecl; external SDL_LibName;

Reallocate memory obtained from SDL_SIMDAlloc. It is not valid to use this function on a pointer from anything but SDL_SIMDAlloc(). It can't be used on pointers from SDL_malloc, GetMem, etc.

Types

cwchar_t = UnixType.wchar_t;

wchar_t is the "wide character" type of the C language. The size of this type is platform- and compiler-dependent. While FPC does have it's own "wide character" type, System.WideChar, that one is defined as always being 16-bits, so we can't re-use it here. When using FPC on Unices, the UnixType unit provides a wchar_t definition. On other systems/compiler combos, let's just go by what the CPP reference wiki claims, i.e: - wchar_t is 16-bits on Windows - wchar_t is 32-bits on Linux "and many other non-Windows systems" See: https://en.cppreference.com/w/cpp/language/types#Character_types

PPSDL_GUID = ˆPSDL_GUID;

An SDL_GUID is a 128-bit identifier for an input device that identifies that device across runs of SDL programs on the same platform. If the device is detached and then re-attached to a different port, or if the base system is rebooted, the device should still report the same GUID. GUIDs are as precise as possible but are not guaranteed to distinguish physically distinct but equivalent devices. For example, two game controllers from the same vendor with the same product ID and revision may have the same GUID. GUIDs may be platform-dependent (i.e., the same device may report different GUIDs on different operating systems).

PPSDL_Haptic = ˆPSDL_Haptic;

SDL_Haptic The haptic structure used to identify an SDL haptic. SDL_HapticOpen SDL_HapticOpenFromJoystick SDL_HapticClose

PPSDL_HapticCondition = ˆPSDL_HapticCondition;

A structure containing a template for a Condition effect. The struct handles the following effects: - SDL_HAPTIC_SPRING: Effect based on axes position. - SDL_HAPTIC_DAMPER: Effect based on axes velocity. - SDL_HAPTIC_INERTIA: Effect based on axes acceleration. - SDL_HAPTIC_FRICTION: Effect based on axes movement. Direction is handled by condition internals instead of a direction member. The condition effect specific members have three parameters. The first refers to the X axis, the second refers to the Y axis and the third refers to the Z axis. The right terms refer to the positive side of the axis and the left terms refer to the negative side of the axis. Please refer to the ::SDL_HapticDirection diagram for which side is positive and which is negative. SDL_HapticDirection SDL_HAPTIC_SPRING SDL_HAPTIC_DAMPER SDL_HAPTIC_INERTIA SDL_HAPTIC_FRICTION SDL_HapticEffect

PPSDL_HapticConstant = ˆPSDL_HapticConstant;

A structure containing a template for a Constant effect. The struct is exclusive to the ::SDL_HAPTIC_CONSTANT effect. A constant effect applies a constant force in the specified direction to the joystick. SDL_HAPTIC_CONSTANT SDL_HapticEffect

PPSDL_HapticCustom = ˆPSDL_HapticCustom;

A structure containing a template for the ::SDL_HAPTIC_CUSTOM effect. A custom force feedback effect is much like a periodic effect, where the application can define its exact shape. You will have to allocate the data yourself. Data should consist of channels * samples Uint16 samples. If channels is one, the effect is rotated using the defined direction. Otherwise it uses the samples in data for the different axes. SDL_HAPTIC_CUSTOM SDL_HapticEffect

PPSDL_HapticDirection = ˆPSDL_HapticDirection;

Structure that represents a haptic direction. Directions can be specified by: - SDL_HAPTIC_POLAR : Specified by polar coordinates. - SDL_HAPTIC_CARTESIAN : Specified by cartesian coordinates. - SDL_HAPTIC_SPHERICAL : Specified by spherical coordinates. Cardinal directions of the haptic device are relative to the positioning of the device. North is considered to be away from the user. The following diagram represents the cardinal directions: .–. |__| .——-. |=.| |.—–.| |–| || || | | |'—–'| |__|˜')_____(' [ COMPUTER ] North (0,-1) ˆ | | (1,0) West <—-[ HAPTIC ]—-> East (-1,0) | | v South (0,1) [ USER ] \|||/ (o o) —ooO-(_)-Ooo— If type is SDL_HAPTIC_POLAR, direction is encoded by hundredths of a degree starting north and turning clockwise. ::SDL_HAPTIC_POLAR only uses the first dir parameter. The cardinal directions would be: - North: 0 (0 degrees) - East: 9000 (90 degrees) - South: 18000 (180 degrees) - West: 27000 (270 degrees) If type is SDL_HAPTIC_CARTESIAN, direction is encoded by three positions (X axis, Y axis and Z axis (with 3 axes)). ::SDL_HAPTIC_CARTESIAN uses the first three dir parameters. The cardinal directions would be: - North: 0,-1, 0 - East: -1, 0, 0 - South: 0, 1, 0 - West: 1, 0, 0 The Z axis represents the height of the effect if supported, otherwise it's unused. In cartesian encoding (1, 2) would be the same as (2, 4), you can use any multiple you want, only the direction matters. If type is SDL_HAPTIC_SPHERICAL, direction is encoded by two rotations. The first two dir parameters are used. The dir parameters are as follows (all values are in hundredths of degrees): - Degrees from (1, 0) rotated towards (0, 1). - Degrees towards (0, 0, 1) (device needs at least 3 axes). Example of force coming from the south with all encodings (force coming from the south means the user will have to pull the stick to counteract): SDL_HapticDirection direction; // Cartesian directions direction.type = SDL_HAPTIC_CARTESIAN; // Using cartesian direction encoding. direction.dir[0] = 0; // X position direction.dir[1] = 1; // Y position // Assuming the device has 2 axes, we don't need to specify third parameter. // Polar directions direction.type = SDL_HAPTIC_POLAR; // We'll be using polar direction encoding. direction.dir[0] = 18000; // Polar only uses first parameter // Spherical coordinates direction.type = SDL_HAPTIC_SPHERICAL; // Spherical encoding direction.dir[0] = 9000; // Since we only have two axes we don't need more parameters. SDL_HAPTIC_POLAR SDL_HAPTIC_CARTESIAN SDL_HAPTIC_SPHERICAL SDL_HapticEffect SDL_HapticNumAxes

PPSDL_HapticEffect = ˆPSDL_HapticEffect;

The generic template for any haptic effect. All values max at 32767 (0x7FFF). Signed values also can be negative. Time values unless specified otherwise are in milliseconds. You can also pass SDL_HAPTIC_INFINITY to length instead of a 0-32767 value. Neither delay, interval, attack_length nor fade_length support SDL_HAPTIC_INFINITY. Fade will also not be used since effect never ends. Additionally, the SDL_HAPTIC_RAMP effect does not support a duration of SDL_HAPTIC_INFINITY. Button triggers may not be supported on all devices, it is advised to not use them if possible. Buttons start at index 1 instead of index 0 like the joystick. If both attack_length and fade_level are 0, the envelope is not used, otherwise both values are used. Common parts: // Replay - All effects have this Uint32 length; // Duration of effect (ms). Uint16 delay; // Delay before starting effect. // Trigger - All effects have this Uint16 button; // Button that triggers effect. Uint16 interval; // How soon before effect can be triggered again. // Envelope - All effects except condition effects have this Uint16 attack_length; // Duration of the attack (ms). Uint16 attack_level; // Level at the start of the attack. Uint16 fade_length; // Duration of the fade out (ms). Uint16 fade_level; // Level at the end of the fade. Here we have an example of a constant effect evolution in time: Strength ˆ | | effect level –> _________________ | / \ | / \ | / \ | / \ | attack_level –> | \ | | | <— fade_level | +————————————————–> Time [–] [—] attack_length fade_length [——————][———————–] delay length Note either the attack_level or the fade_level may be above the actual effect level. SDL_HapticConstant SDL_HapticPeriodic SDL_HapticCondition SDL_HapticRamp SDL_HapticCustom

PPSDL_HapticPeriodic = ˆPSDL_HapticPeriodic;

A structure containing a template for a Periodic effect. The struct handles the following effects: - SDL_HAPTIC_SINE - SDL_HAPTIC_SQUARE - SDL_HAPTIC_TRIANGLE - SDL_HAPTIC_SAWTOOTHUP - SDL_HAPTIC_SAWTOOTHDOWN A periodic effect consists in a wave-shaped effect that repeats itself over time. The type determines the shape of the wave and the parameters determine the dimensions of the wave. Phase is given by hundredth of a cycle meaning that giving the phase a value of 9000 will displace it 25% of its period. Here are sample values: - 0: No phase displacement. - 9000: Displaced 25% of its period. - 18000: Displaced 50% of its period. - 27000: Displaced 75% of its period. - 36000: Displaced 100% of its period, same as 0, but 0 is preferred. Examples: SDL_HAPTIC_SINE __ __ __ __ / \ / \ / \ / / \__/ \__/ \__/ SDL_HAPTIC_SQUARE __ __ __ __ __ | | | | | | | | | | | |__| |__| |__| |__| | SDL_HAPTIC_TRIANGLE /\ /\ /\ /\ /\ / \ / \ / \ / \ / / \/ \/ \/ \/ SDL_HAPTIC_SAWTOOTHUP /| /| /| /| /| /| /| / | / | / | / | / | / | / | / |/ |/ |/ |/ |/ |/ | SDL_HAPTIC_SAWTOOTHDOWN \ |\ |\ |\ |\ |\ |\ | \ | \ | \ | \ | \ | \ | \ | \| \| \| \| \| \| \| SDL_HAPTIC_SINE SDL_HAPTIC_SQUARE SDL_HAPTIC_TRIANGLE SDL_HAPTIC_SAWTOOTHUP SDL_HAPTIC_SAWTOOTHDOWN SDL_HapticEffect

PPSDL_HapticRamp = ˆPSDL_HapticRamp;

SDL_HINT_THREAD_PRIORITY_POLICY can be used to control aspects of this behavior. \note On many systems you require special privileges to set high or time critical priority.

PPSDL_TimerCallback = ˆPSDL_TimerCallback;

Function prototype for the timer callback function. The callback function is passed the current timer interval and returns the next timer interval.

SDL_CondSignal(cond); SDL_UnlockMutex(lock); There is some discussion whether to signal the condition variable with the mutex locked or not. There is some potential performance benefit to unlocking first on some platforms, but there are some potential race conditions depending on how your code is structured. In general it's safer to signal the condition variable while the mutex is locked.

SDL_HINT_APP_NAME = 'SDL_APP_NAME';

\brief Specify an application name. This hint lets you specify the application name sent to the OS when required. For example, this will often appear in volume control applets for audio streams, and in lists of applications which are inhibiting the screensaver. You should use a string that describes your program ("My Game 2: The Revenge") Setting this to "" or leaving it unset will have SDL use a reasonable default: probably the application's name or "SDL Application" if SDL doesn't have any better information. Note that, for audio streams, this can be overridden with SDL_HINT_AUDIO_DEVICE_APP_NAME. On targets where this is not supported, this hint does nothing.

SDL_HINT_AUDIODRIVER = 'SDL_AUDIODRIVER';

\brief A variable that decides what audio backend to use. By default, SDL will try all available audio backends in a reasonable order until it finds one that can work, but this hint allows the app or user to force a specific target, such as "alsa" if, say, you are on PulseAudio but want to try talking to the lower level instead. This functionality has existed since SDL 2.0.0 (indeed, before that) but before 2.0.22 this was an environment variable only. In 2.0.22, it was upgraded to a full SDL hint, so you can set the environment variable as usual or programatically set the hint with SDL_SetHint, which won't propagate to child processes. The default value is unset, in which case SDL will try to figure out the best audio backend on your behalf. This hint needs to be set before SDL_Init() is called to be useful. This hint is available since SDL 2.0.22. Before then, you could set the environment variable to get the same effect.

/** \brief A variable that causes SDL to not ignore audio "monitors" This is currently only used for PulseAudio and ignored elsewhere. By default, SDL ignores audio devices that aren't associated with physical hardware. Changing this hint to "1" will expose anything SDL sees that appears to be an audio source or sink. This will add "devices" to the list that the user probably doesn't want or need, but it can be useful in scenarios where you want to hook up SDL to some sort of virtual device, etc. The default value is "0". This hint must be set before SDL_Init(). This hint is available since SDL 2.0.16. Before then, virtual devices are always ignored. /

If this hint isn't specified to a valid setting, or libsamplerate isn't available, SDL will use the default, internal resampling algorithm. Note that this is currently only applicable to resampling audio that is being written to a device for playback or audio being read from a device for capture. SDL_AudioCVT always uses the default resampler (although this might change for SDL 2.1). This hint is currently only checked at audio subsystem initialization. This variable can be set to the following values: "0" or "default" - Use SDL's internal resampling (Default when not set - low quality, fast) "1" or "fast" - Use fast, slightly higher quality resampling, if available "2" or "medium" - Use medium quality resampling, if available "3" or "best" - Use high quality resampling, if available /

The variable can be set to the following values: "0" - Surfaces with a colorkey or an alpha channel are saved to a 32-bit BMP file with an alpha mask. SDL will use the bitmap header version 4 and set the alpha mask accordingly. "1" - Surfaces with a colorkey or an alpha channel are saved to a 32-bit BMP file without an alpha mask.

This is generally meant to be used to debug SDL itself, but can be useful for application developers that need better visibility into what is going on in the event queue. Logged events are sent through SDL_Log(), which means by default they appear on stdout on most platforms or maybe OutputDebugString() on Windows, and can be funneled by the app with SDL_LogSetOutputFunction(), etc. This hint can be toggled on and off at runtime, if you only need to log events for a small subset of program execution. /

/** \brief A variable controlling which orientations are allowed on iOS. In some circumstances it is necessary to be able to explicitly control which UI orientations are allowed. This variable is a space delimited list of the following values: "LandscapeLeft", "LandscapeRight", "Portrait" "PortraitUpsideDown" /

SDL_HINT_OVERRIDE = TSDL_HintPriority(2);

SDL_HINT_POLL_SENTINEL = 'SDL_POLL_SENTINEL';

/** \brief A variable controlling the use of a sentinel event when polling the event queue This variable can be set to the following values: "0" - Disable poll sentinels "1" - Enable poll sentinels When polling for events, SDL_PumpEvents is used to gather new events from devices. If a device keeps producing new events between calls to SDL_PumpEvents, a poll loop will become stuck until the new events stop. This is most noticable when moving a high frequency mouse. By default, poll sentinels are enabled. /

SDL_HINT_PREFERRED_LOCALES = 'SDL_PREFERRED_LOCALES';

/** \brief Override for SDL_GetPreferredLocales() If set, this will be favored over anything the OS might report for the user's preferred locales. Changing this hint at runtime will not generate a SDL_LOCALECHANGED event (but if you can change the hint, you can push your own event, if you want). The format of this hint is a comma-separated list of language and locale, combined with an underscore, as is a common format: "en_GB". Locale is optional: "en". So you might have a list like this: "en_GB,jp,es_PT" /

SDL_HINT_PS2_DYNAMIC_VSYNC = 'SDL_PS2_DYNAMIC_VSYNC';

\brief A variable controlling if VSYNC is automatically disable if doesn't reach the enough FPS This variable can be set to the following values: "0" - It will be using VSYNC as defined in the main flag. Default "1" - If VSYNC was previously enabled, then it will disable VSYNC if doesn't reach enough speed By default SDL does not enable the automatic VSYNC

SDL_HINT_QTWAYLAND_CONTENT_ORIENTATION = 'SDL_QTWAYLAND_CONTENT_ORIENTATION';

/** \brief A variable describing the content orientation on QtWayland-based platforms. On QtWayland platforms, windows are rotated client-side to allow for custom transitions. In order to correctly position overlays (e.g. volume bar) and gestures (e.g. events view, close/minimize gestures), the system needs to know in which orientation the application is currently drawing its contents. This does not cause the window to be rotated or resized, the application needs to take care of drawing the content in the right orientation (the framebuffer is always in portrait mode). This variable can be one of the following values: "primary" (default), "portrait", "landscape", "inverted-portrait", "inverted-landscape" /

SDL_HINT_QTWAYLAND_WINDOW_FLAGS = 'SDL_QTWAYLAND_WINDOW_FLAGS';

/** \brief Flags to set on QtWayland windows to integrate with the native window manager. On QtWayland platforms, this hint controls the flags to set on the windows. For example, on Sailfish OS "OverridesSystemGestures" disables swipe gestures. This variable is a space-separated list of the following values (empty = no flags): "OverridesSystemGestures", "StaysOnTop", "BypassWindowManager" /

SDL_HINT_QUIT_ON_LAST_WINDOW_CLOSE = 'SDL_QUIT_ON_LAST_WINDOW_CLOSE';

\brief A variable that decides whether to send SDL_QUIT when closing the final window. By default, SDL sends an SDL_QUIT event when there is only one window and it receives an SDL_WINDOWEVENT_CLOSE event, under the assumption most apps would also take the loss of this window as a signal to terminate the program. However, it's not unreasonable in some cases to have the program continue to live on, perhaps to create new windows later. Changing this hint to "0" will cause SDL to not send an SDL_QUIT event when the final window is requesting to close. Note that in this case, there are still other legitimate reasons one might get an SDL_QUIT event: choosing "Quit" from the macOS menu bar, sending a SIGINT (ctrl-c) on Unix, etc. The default value is "1". This hint can be changed at any time. This hint is available since SDL 2.0.22. Before then, you always get an SDL_QUIT event when closing the final window.

SDL_HINT_RENDER_BATCHING = 'SDL_RENDER_BATCHING';

/** \brief A variable controlling whether the 2D render API is compatible or efficient. This variable can be set to the following values: "0" - Don't use batching to make rendering more efficient. "1" - Use batching, but might cause problems if app makes its own direct OpenGL calls. Up to SDL 2.0.9, the render API would draw immediately when requested. Now it batches up draw requests and sends them all to the GPU only when forced to (during SDL_RenderPresent, when changing render targets, by updating a texture that the batch needs, etc). This is significantly more efficient, but it can cause problems for apps that expect to render on top of the render API's output. As such, SDL will disable batching if a specific render backend is requested (since this might indicate that the app is planning to use the underlying graphics API directly). This hint can be used to explicitly request batching in this instance. It is a contract that you will either never use the underlying graphics API directly, or if you do, you will call SDL_RenderFlush() before you do so any current batch goes to the GPU before your work begins. Not following this contract will result in undefined behavior. /

SDL_HINT_RENDER_DIRECT3D11_DEBUG = 'SDL_RENDER_DIRECT3D11_DEBUG';

/** \brief A variable controlling whether to enable Direct3D 11+'s Debug Layer. This variable does not have any effect on the Direct3D 9 based renderer.

SDL_HINT_RENDER_DIRECT3D_THREADSAFE = 'SDL_RENDER_DIRECT3D_THREADSAFE';

/** \brief A variable controlling whether the Direct3D device is initialized for thread-safe operations. This variable can be set to the following values: "0" - Thread-safety is not enabled (faster) "1" - Thread-safety is enabled By default the Direct3D device is created with thread-safety disabled. /

SDL_HINT_RENDER_DRIVER = 'SDL_RENDER_DRIVER';

/** \brief A variable specifying which render driver to use. If the application doesn't pick a specific renderer to use, this variable specifies the name of the preferred renderer. If the preferred renderer can't be initialized, the normal default renderer is used. This variable is case insensitive and can be set to the following values: "direct3d" "opengl" "opengles2" "opengles" "software" The default varies by platform, but it's the first one in the list that is available on the current platform. /

SDL_HINT_RENDER_LINE_METHOD = 'SDL_RENDER_LINE_METHOD';

/** \brief A variable controlling how the 2D render API renders lines This variable can be set to the following values: "0" - Use the default line drawing method (Bresenham's line algorithm as of SDL 2.0.20) "1" - Use the driver point API using Bresenham's line algorithm (correct, draws many points) "2" - Use the driver line API (occasionally misses line endpoints based on hardware driver quirks, was the default before 2.0.20) "3" - Use the driver geometry API (correct, draws thicker diagonal lines) This variable should be set when the renderer is created. /

SDL_HINT_RENDER_LOGICAL_SIZE_MODE = 'SDL_RENDER_LOGICAL_SIZE_MODE';

/** \brief A variable controlling the scaling policy for SDL_RenderSetLogicalSize. This variable can be set to the following values: "0" or "letterbox" - Uses letterbox/sidebars to fit the entire rendering on screen "1" or "overscan" - Will zoom the rendering so it fills the entire screen, allowing edges to be drawn offscreen By default letterbox is used /

SDL_HINT_RENDER_OPENGL_SHADERS = 'SDL_RENDER_OPENGL_SHADERS';

/** \brief A variable controlling whether the OpenGL render driver uses shaders if they are available. This variable can be set to the following values: "0" - Disable shaders "1" - Enable shaders By default shaders are used if OpenGL supports them. /

SDL_HINT_RENDER_SCALE_QUALITY = 'SDL_RENDER_SCALE_QUALITY';

/** \brief A variable controlling the scaling quality This variable can be set to the following values: "0" or "nearest" - Nearest pixel sampling "1" or "linear" - Linear filtering (supported by OpenGL and Direct3D) "2" or "best" - Currently this is the same as "linear" By default nearest pixel sampling is used /

SDL_HINT_RENDER_VSYNC = 'SDL_RENDER_VSYNC';

/** \brief A variable controlling whether updates to the SDL screen surface should be synchronized with the vertical refresh, to avoid tearing. This variable can be set to the following values: "0" - Disable vsync "1" - Enable vsync By default SDL does not sync screen surface updates with vertical refresh. /

SDL_HINT_RETURN_KEY_HIDES_IME = 'SDL_RETURN_KEY_HIDES_IME';

/** \brief A variable to control whether the return key on the soft keyboard should hide the soft keyboard on Android and iOS. The variable can be set to the following values: "0" - The return key will be handled as a key event. This is the behaviour of SDL <= 2.0.3. (default) "1" - The return key will hide the keyboard. The value of this hint is used at runtime, so it can be changed at any time. /

SDL_HINT_RPI_VIDEO_LAYER = 'SDL_RPI_VIDEO_LAYER';

/** \brief Tell SDL which Dispmanx layer to use on a Raspberry PI Also known as Z-order. The variable can take a negative or positive value. The default is 10000. /

SDL_HINT_SCREENSAVER_INHIBIT_ACTIVITY_NAME = 'SDL_SCREENSAVER_INHIBIT_ACTIVITY_NAME';

/** \brief Specify an "activity name" for screensaver inhibition. Some platforms, notably Linux desktops, list the applications which are inhibiting the screensaver or other power-saving features. This hint lets you specify the "activity name" sent to the OS when SDL_DisableScreenSaver() is used (or the screensaver is automatically disabled). The contents of this hint are used when the screensaver is disabled. You should use a string that describes what your program is doing (and, therefore, why the screensaver is disabled). For example, "Playing a game" or "Watching a video". Setting this to "" or leaving it unset will have SDL use a reasonable default: "Playing a game" or something similar. On targets where this is not supported, this hint does nothing. /

SDL_HINT_THREAD_FORCE_REALTIME_TIME_CRITICAL = 'SDL_THREAD_FORCE_REALTIME_TIME_CRITICAL';

/** \brief Specifies whether SDL_THREAD_PRIORITY_TIME_CRITICAL should be treated as realtime. On some platforms, like Linux, a realtime priority thread may be subject to restrictions that require special handling by the application. This hint exists to let SDL know that the app is prepared to handle said restrictions. On Linux, SDL will apply the following configuration to any thread that becomes realtime: * The SCHED_RESET_ON_FORK bit will be set on the scheduling policy, * An RLIMIT_RTTIME budget will be configured to the rtkit specified limit. * Exceeding this limit will result in the kernel sending SIGKILL to the app, * Refer to the man pages for more information. This variable can be set to the following values: "0" - default platform specific behaviour "1" - Force SDL_THREAD_PRIORITY_TIME_CRITICAL to a realtime scheduling policy /

SDL_HINT_THREAD_PRIORITY_POLICY = 'SDL_THREAD_PRIORITY_POLICY';

/** \brief A string specifying additional information to use with SDL_SetThreadPriority. By default SDL_SetThreadPriority will make appropriate system changes in order to apply a thread priority. For example on systems using pthreads the scheduler policy is changed automatically to a policy that works well with a given priority. Code which has specific requirements can override SDL's default behavior with this hint. pthread hint values are "current", "other", "fifo" and "rr". Currently no other platform hint values are defined but may be in the future. \note On Linux, the kernel may send SIGKILL to realtime tasks which exceed the distro configured execution budget for rtkit. This budget can be queried through RLIMIT_RTTIME after calling SDL_SetThreadPriority(). /

SDL_HINT_THREAD_STACK_SIZE = 'SDL_THREAD_STACK_SIZE';

/** \brief A string specifying SDL's threads stack size in bytes or "0" for the backend's default size Use this hint in case you need to set SDL's threads stack size to other than the default. This is specially useful if you build SDL against a non glibc libc library (such as musl) which provides a relatively small default thread stack size (a few kilobytes versus the default 8MB glibc uses). Support for this hint is currently available only in the pthread, Windows, and PSP backend. /

SDL_HINT_TIMER_RESOLUTION = 'SDL_TIMER_RESOLUTION';

/** \brief A variable that controls the timer resolution, in milliseconds. The higher resolution the timer, the more frequently the CPU services timer interrupts, and the more precise delays are, but this takes up power and CPU time. This hint is only used on Windows 7 and earlier. See this blog post for more information: http://randomascii.wordpress.com/2013/07/08/windows-timer-resolution-megawatts-wasted/ If this variable is set to "0", the system timer resolution is not set. The default value is "1". This hint may be set at any time. /

SDL_HINT_TOUCH_MOUSE_EVENTS = 'SDL_TOUCH_MOUSE_EVENTS';

/** \brief A variable controlling whether touch events should generate synthetic mouse events This variable can be set to the following values: "0" - Touch events will not generate mouse events "1" - Touch events will generate mouse events By default SDL will generate mouse events for touch events /

SDL_HINT_TRACKPAD_IS_TOUCH_ONLY = 'SDL_TRACKPAD_IS_TOUCH_ONLY';

\brief A variable that treats trackpads as touch devices. On macOS (and possibly other platforms in the future), SDL will report touches on a trackpad as mouse input, which is generally what users expect from this device; however, these are often actually full multitouch-capable touch devices, so it might be preferable to some apps to treat them as such. Setting this hint to true will make the trackpad input report as a multitouch device instead of a mouse. The default is false. Note that most platforms don't support this hint. As of 2.24.0, it only supports MacBooks' trackpads on macOS. Others may follow later. This hint is checked during SDL_Init and can not be changed after. This hint is available since SDL 2.24.0.

SDL_HINT_TV_REMOTE_AS_JOYSTICK = 'SDL_TV_REMOTE_AS_JOYSTICK';

/** \brief A variable controlling whether the Android / tvOS remotes should be listed as joystick devices, instead of sending keyboard events. This variable can be set to the following values: "0" - Remotes send enter/escape/arrow key events "1" - Remotes are available as 2 axis, 2 button joysticks (the default). /

SDL_HINT_VIDEODRIVER = 'SDL_VIDEODRIVER';

\brief A variable that decides what video backend to use. By default, SDL will try all available video backends in a reasonable order until it finds one that can work, but this hint allows the app or user to force a specific target, such as "x11" if, say, you are on Wayland but want to try talking to the X server instead. This functionality has existed since SDL 2.0.0 (indeed, before that) but before 2.0.22 this was an environment variable only. In 2.0.22, it was upgraded to a full SDL hint, so you can set the environment variable as usual or programatically set the hint with SDL_SetHint, which won't propagate to child processes. The default value is unset, in which case SDL will try to figure out the best video backend on your behalf. This hint needs to be set before SDL_Init() is called to be useful. This hint is available since SDL 2.0.22. Before then, you could set the environment variable to get the same effect.

SDL_HINT_VIDEO_ALLOW_SCREENSAVER = 'SDL_VIDEO_ALLOW_SCREENSAVER';

/** \brief A variable controlling whether the screensaver is enabled. This variable can be set to the following values: "0" - Disable screensaver "1" - Enable screensaver By default SDL will disable the screensaver. /

SDL_HINT_VIDEO_DOUBLE_BUFFER = 'SDL_VIDEO_DOUBLE_BUFFER';

/** \brief Tell the video driver that we only want a double buffer. By default, most lowlevel 2D APIs will use a triple buffer scheme that wastes no CPU time on waiting for vsync after issuing a flip, but introduces a frame of latency. On the other hand, using a double buffer scheme instead is recommended for cases where low latency is an important factor because we save a whole frame of latency. We do so by waiting for vsync immediately after issuing a flip, usually just after eglSwapBuffers call in the backend's *_SwapWindow function. Since it's driver-specific, it's only supported where possible and implemented. Currently supported the following drivers: - KMSDRM (kmsdrm) - Raspberry Pi (raspberrypi) /

SDL_HINT_VIDEO_EGL_ALLOW_TRANSPARENCY = 'SDL_VIDEO_EGL_ALLOW_TRANSPARENCY';

/** \brief A variable controlling whether the EGL window is allowed to be composited as transparent, rather than opaque. Most window systems will always render windows opaque, even if the surface format has an alpha channel. This is not always true, however, so by default SDL will try to enforce opaque composition. To override this behavior, you can set this hint to "1". /

SDL_HINT_VIDEO_EXTERNAL_CONTEXT = 'SDL_VIDEO_EXTERNAL_CONTEXT';

/** \brief A variable controlling whether the graphics context is externally managed. This variable can be set to the following values: "0" - SDL will manage graphics contexts that are attached to windows. "1" - Disable graphics context management on windows. By default SDL will manage OpenGL contexts in certain situations. For example, on Android the context will be automatically saved and restored when pausing the application. Additionally, some platforms will assume usage of OpenGL if Vulkan isn't used. Setting this to "1" will prevent this behavior, which is desireable when the application manages the graphics context, such as an externally managed OpenGL context or attaching a Vulkan surface to the window. /

SDL_HINT_VIDEO_FOREIGN_WINDOW_OPENGL = 'SDL_VIDEO_FOREIGN_WINDOW_OPENGL';

\brief When calling SDL_CreateWindowFrom(), make the window compatible with OpenGL. This variable can be set to the following values: "0" - Don't add any graphics flags to the SDL_WindowFlags "1" - Add SDL_WINDOW_OPENGL to the SDL_WindowFlags By default SDL will not make the foreign window compatible with OpenGL.

SDL_HINT_VIDEO_FOREIGN_WINDOW_VULKAN = 'SDL_VIDEO_FOREIGN_WINDOW_VULKAN';

\brief When calling SDL_CreateWindowFrom(), make the window compatible with Vulkan. This variable can be set to the following values: "0" - Don't add any graphics flags to the SDL_WindowFlags "1" - Add SDL_WINDOW_VULKAN to the SDL_WindowFlags By default SDL will not make the foreign window compatible with Vulkan.

SDL_HINT_VIDEO_HIGHDPI_DISABLED = 'SDL_VIDEO_HIGHDPI_DISABLED';

/** \brief If set to 1, then do not allow high-DPI windows. ("Retina" on Mac and iOS) /

SDL_HINT_VIDEO_MAC_FULLSCREEN_SPACES = 'SDL_VIDEO_MAC_FULLSCREEN_SPACES';

/** \brief A variable that dictates policy for fullscreen Spaces on Mac OS X. This hint only applies to Mac OS X. The variable can be set to the following values: "0" - Disable Spaces support (FULLSCREEN_DESKTOP won't use them and SDL_WINDOW_RESIZABLE windows won't offer the "fullscreen" button on their titlebars). "1" - Enable Spaces support (FULLSCREEN_DESKTOP will use them and SDL_WINDOW_RESIZABLE windows will offer the "fullscreen" button on their titlebars). The default value is "1". Spaces are disabled regardless of this hint if the OS isn't at least Mac OS X Lion (10.7). This hint must be set before any windows are created. /

SDL_HINT_VIDEO_MINIMIZE_ON_FOCUS_LOSS = 'SDL_VIDEO_MINIMIZE_ON_FOCUS_LOSS';

/** \brief Minimize your SDL_Window if it loses key focus when in Fullscreen mode. Defaults to true. /

SDL_HINT_VIDEO_WAYLAND_ALLOW_LIBDECOR = 'SDL_VIDEO_WAYLAND_ALLOW_LIBDECOR';

/** \brief A variable controlling whether the libdecor Wayland backend is allowed to be used. This variable can be set to the following values: "0" - libdecor use is disabled. "1" - libdecor use is enabled (default). libdecor is used over xdg-shell when xdg-decoration protocol is unavailable. /

SDL_HINT_VIDEO_WAYLAND_EMULATE_MOUSE_WARP = 'SDL_VIDEO_WAYLAND_EMULATE_MOUSE_WARP';

\brief Enable or disable mouse pointer warp emulation, needed by some older games. When this hint is set, any SDL will emulate mouse warps using relative mouse mode. This is required for some older games (such as Source engine games), which warp the mouse to the centre of the screen rather than using relative mouse motion. Note that relative mouse mode may have different mouse acceleration behaviour than pointer warps. This variable can be set to the following values: "0" - All mouse warps fail, as mouse warping is not available under Wayland. "1" - Some mouse warps will be emulated by forcing relative mouse mode. If not set, this is automatically enabled unless an application uses relative mouse mode directly. This hint is available since SDL 2.26.0.

SDL_HINT_VIDEO_WAYLAND_MODE_EMULATION = 'SDL_VIDEO_WAYLAND_MODE_EMULATION';

\brief A variable controlling whether video mode emulation is enabled under Wayland. When this hint is set, a standard set of emulated CVT video modes will be exposed for use by the application. If it is disabled, the only modes exposed will be the logical desktop size and, in the case of a scaled desktop, the native display resolution. This variable can be set to the following values: "0" - Video mode emulation is disabled. "1" - Video mode emulation is enabled. By default video mode emulation is enabled.

SDL_HINT_VIDEO_WAYLAND_PREFER_LIBDECOR = 'SDL_VIDEO_WAYLAND_PREFER_LIBDECOR';

\brief A variable controlling whether the libdecor Wayland backend is preferred over native decrations. When this hint is set, libdecor will be used to provide window decorations, even if xdg-decoration is available. (Note that, by default, libdecor will use xdg-decoration itself if available). This variable can be set to the following values: "0" - libdecor is enabled only if server-side decorations are unavailable. "1" - libdecor is always enabled if available. libdecor is used over xdg-shell when xdg-decoration protocol is unavailable.

SDL_HINT_VIDEO_WINDOW_SHARE_PIXEL_FORMAT = 'SDL_VIDEO_WINDOW_SHARE_PIXEL_FORMAT';

/** \brief A variable that is the address of another SDL_Window* (as a hex string formatted with "%p"). If this hint is set before SDL_CreateWindowFrom() and the SDL_Window* it is set to has SDL_WINDOW_OPENGL set (and running on WGL only, currently), then two things will occur on the newly created SDL_Window: 1. Its pixel format will be set to the same pixel format as this SDL_Window. This is needed for example when sharing an OpenGL context across multiple windows. 2. The flag SDL_WINDOW_OPENGL will be set on the new window so it can be used for OpenGL rendering. This variable can be set to the following values: The address (as a string "%p") of the SDL_Window* that new windows created with SDL_CreateWindowFrom() should share a pixel format with. /

SDL_HINT_VIDEO_WIN_D3DCOMPILER = 'SDL_VIDEO_WIN_D3DCOMPILER';

/** \brief A variable specifying which shader compiler to preload when using the Chrome ANGLE binaries SDL has EGL and OpenGL ES2 support on Windows via the ANGLE project. It can use two different sets of binaries, those compiled by the user from source or those provided by the Chrome browser. In the later case, these binaries require that SDL loads a DLL providing the shader compiler. This variable can be set to the following values: "d3dcompiler_46.dll" - default, best for Vista or later. "d3dcompiler_43.dll" - for XP support. "none" - do not load any library, useful if you compiled ANGLE from source and included the compiler in your binaries. /

SDL_HINT_VIDEO_X11_FORCE_EGL = 'SDL_VIDEO_X11_FORCE_EGL';

/** \brief A variable controlling whether X11 should use GLX or EGL by default This variable can be set to the following values: "0" - Use GLX "1" - Use EGL By default SDL will use GLX when both are present. /

SDL_HINT_VIDEO_X11_NET_WM_BYPASS_COMPOSITOR = 'SDL_VIDEO_X11_NET_WM_BYPASS_COMPOSITOR';

/** \brief A variable controlling whether the X11 _NET_WM_BYPASS_COMPOSITOR hint should be used. This variable can be set to the following values: "0" - Disable _NET_WM_BYPASS_COMPOSITOR "1" - Enable _NET_WM_BYPASS_COMPOSITOR By default SDL will use _NET_WM_BYPASS_COMPOSITOR /

SDL_HINT_VIDEO_X11_NET_WM_PING = 'SDL_VIDEO_X11_NET_WM_PING';

/** \brief A variable controlling whether the X11 _NET_WM_PING protocol should be supported. This variable can be set to the following values: "0" - Disable _NET_WM_PING "1" - Enable _NET_WM_PING By default SDL will use _NET_WM_PING, but for applications that know they will not always be able to respond to ping requests in a timely manner they can turn it off to avoid the window manager thinking the app is hung. The hint is checked in CreateWindow. /

SDL_HINT_VIDEO_X11_WINDOW_VISUALID = 'SDL_VIDEO_X11_WINDOW_VISUALID';

/** \brief A variable forcing the visual ID chosen for new X11 windows /

SDL_HINT_VIDEO_X11_XINERAMA = 'SDL_VIDEO_X11_XINERAMA';

/** \brief A variable controlling whether the X11 Xinerama extension should be used. This variable can be set to the following values: "0" - Disable Xinerama "1" - Enable Xinerama By default SDL will use Xinerama if it is available. /

/** \brief A variable controlling whether the X11 XRandR extension should be used. This variable can be set to the following values: "0" - Disable XRandR "1" - Enable XRandR By default SDL will not use XRandR because of window manager issues. /

SDL_HINT_VIDEO_X11_XVIDMODE = 'SDL_VIDEO_X11_XVIDMODE';

/** \brief A variable controlling whether the X11 VidMode extension should be used. This variable can be set to the following values: "0" - Disable XVidMode "1" - Enable XVidMode By default SDL will use XVidMode if it is available. /

SDL_HINT_VITA_TOUCH_MOUSE_DEVICE = 'SDL_HINT_VITA_TOUCH_MOUSE_DEVICE';

\brief A variable controlling which touchpad should generate synthetic mouse events This variable can be set to the following values: "0" - Only front touchpad should generate mouse events. Default "1" - Only back touchpad should generate mouse events. "2" - Both touchpads should generate mouse events. By default SDL will generate mouse events for all touch devices

SDL_HINT_WAVE_FACT_CHUNK = 'SDL_WAVE_FACT_CHUNK';

/** \brief Controls how the fact chunk affects the loading of a WAVE file. The fact chunk stores information about the number of samples of a WAVE file. The Standards Update from Microsoft notes that this value can be used to 'determine the length of the data in seconds'. This is especially useful for compressed formats (for which this is a mandatory chunk) if they produce multiple sample frames per block and truncating the block is not allowed. The fact chunk can exactly specify how many sample frames there should be in this case. Unfortunately, most application seem to ignore the fact chunk and so SDL ignores it by default as well. This variable can be set to the following values: "truncate" - Use the number of samples to truncate the wave data if the fact chunk is present and valid "strict" - Like "truncate", but raise an error if the fact chunk is invalid, not present for non-PCM formats, or if the data chunk doesn't have that many samples "ignorezero" - Like "truncate", but ignore fact chunk if the number of samples is zero "ignore" - Ignore fact chunk entirely (default) /

SDL_HINT_WAVE_RIFF_CHUNK_SIZE = 'SDL_WAVE_RIFF_CHUNK_SIZE';

/** \brief Controls how the size of the RIFF chunk affects the loading of a WAVE file. The size of the RIFF chunk (which includes all the sub-chunks of the WAVE file) is not always reliable. In case the size is wrong, it's possible to just ignore it and step through the chunks until a fixed limit is reached. Note that files that have trailing data unrelated to the WAVE file or corrupt files may slow down the loading process without a reliable boundary. By default, SDL stops after 10000 chunks to prevent wasting time. Use the environment variable SDL_WAVE_CHUNK_LIMIT to adjust this value. This variable can be set to the following values: "force" - Always use the RIFF chunk size as a boundary for the chunk search "ignorezero" - Like "force", but a zero size searches up to 4 GiB (default) "ignore" - Ignore the RIFF chunk size and always search up to 4 GiB "maximum" - Search for chunks until the end of file (not recommended) /

SDL_HINT_WAVE_TRUNCATION = 'SDL_WAVE_TRUNCATION';

/** \brief Controls how a truncated WAVE file is handled. A WAVE file is considered truncated if any of the chunks are incomplete or the data chunk size is not a multiple of the block size. By default, SDL decodes until the first incomplete block, as most applications seem to do. This variable can be set to the following values: "verystrict" - Raise an error if the file is truncated "strict" - Like "verystrict", but the size of the RIFF chunk is ignored "dropframe" - Decode until the first incomplete sample frame "dropblock" - Decode until the first incomplete block (default) /

SDL_HINT_WINDOWS_DISABLE_THREAD_NAMING = 'SDL_WINDOWS_DISABLE_THREAD_NAMING';

/** \brief Tell SDL not to name threads on Windows. The variable can be set to the following values: "0" - SDL will raise the 0x406D1388 Exception to name threads. This is the default behavior of SDL <= 2.0.4. (default) "1" - SDL will not raise this exception, and threads will be unnamed. For .NET languages this is required when running under a debugger. /

SDL_HINT_WINDOWS_DPI_AWARENESS = 'SDL_WINDOWS_DPI_AWARENESS';

\brief Controls whether SDL will declare the process to be DPI aware. This hint must be set before initializing the video subsystem. The main purpose of declaring DPI awareness is to disable OS bitmap scaling of SDL windows on monitors with a DPI scale factor. This hint is equivalent to requesting DPI awareness via external means (e.g. calling SetProcessDpiAwarenessContext) and does not cause SDL to use a virtualized coordinate system, so it will generally give you 1 SDL coordinate = 1 pixel even on high-DPI displays. For more information, see: https://docs.microsoft.com/en-us/windows/win32/hidpi/high-dpi-desktop-application-development-on-windows This variable can be set to the following values: "" - Do not change the DPI awareness (default). "unaware" - Declare the process as DPI unaware. (Windows 8.1 and later). "system" - Request system DPI awareness. (Vista and later). "permonitor" - Request per-monitor DPI awareness. (Windows 8.1 and later). "permonitorv2" - Request per-monitor V2 DPI awareness. (Windows 10, version 1607 and later). The most visible difference from "permonitor" is that window title bar will be scaled to the visually correct size when dragging between monitors with different scale factors. This is the preferred DPI awareness level. If the requested DPI awareness is not available on the currently running OS, SDL will try to request the best available match.

SDL_HINT_WINDOWS_DPI_SCALING = 'SDL_WINDOWS_DPI_SCALING';

\brief Uses DPI-scaled points as the SDL coordinate system on Windows. This changes the SDL coordinate system units to be DPI-scaled points, rather than pixels everywhere. This means windows will be appropriately sized, even when created on high-DPI displays with scaling. e.g. requesting a 640x480 window from SDL, on a display with 125% scaling in Windows display settings, will create a window with an 800x600 client area (in pixels). Setting this to "1" implicitly requests process DPI awareness (setting SDL_WINDOWS_DPI_AWARENESS is unnecessary), and forces SDL_WINDOW_ALLOW_HIGHDPI on all windows. This variable can be set to the following values: "0" - SDL coordinates equal Windows coordinates. No automatic window resizing when dragging between monitors with different scale factors (unless this is performed by Windows itself, which is the case when the process is DPI unaware). "1" - SDL coordinates are in DPI-scaled points. Automatically resize windows as needed on displays with non-100% scale factors.

SDL_HINT_WINRT_HANDLE_BACK_BUTTON = 'SDL_WINRT_HANDLE_BACK_BUTTON';

/** \brief Allows back-button-press events on Windows Phone to be marked as handled Windows Phone devices typically feature a Back button. When pressed, the OS will emit back-button-press events, which apps are expected to handle in an appropriate manner. If apps do not explicitly mark these events as 'Handled', then the OS will invoke its default behavior for unhandled back-button-press events, which on Windows Phone 8 and 8.1 is to terminate the app (and attempt to switch to the previous app, or to the device's home screen). Setting the SDL_HINT_WINRT_HANDLE_BACK_BUTTON hint to "1" will cause SDL to mark back-button-press events as Handled, if and when one is sent to the app. Internally, Windows Phone sends back button events as parameters to special back-button-press callback functions. Apps that need to respond to back-button-press events are expected to register one or more callback functions for such, shortly after being launched (during the app's initialization phase). After the back button is pressed, the OS will invoke these callbacks. If the app's callback(s) do not explicitly mark the event as handled by the time they return, or if the app never registers one of these callback, the OS will consider the event un-handled, and it will apply its default back button behavior (terminate the app). SDL registers its own back-button-press callback with the Windows Phone OS. This callback will emit a pair of SDL key-press events (SDL_KEYDOWN and SDL_KEYUP), each with a scancode of SDL_SCANCODE_AC_BACK, after which it will check the contents of the hint, SDL_HINT_WINRT_HANDLE_BACK_BUTTON. If the hint's value is set to "1", the back button event's Handled property will get set to 'true'. If the hint's value is set to something else, or if it is unset, SDL will leave the event's Handled property alone. (By default, the OS sets this property to 'false', to note.) SDL apps can either set SDL_HINT_WINRT_HANDLE_BACK_BUTTON well before a back button is pressed, or can set it in direct-response to a back button being pressed. In order to get notified when a back button is pressed, SDL apps should register a callback function with SDL_AddEventWatch(), and have it listen for SDL_KEYDOWN events that have a scancode of SDL_SCANCODE_AC_BACK. (Alternatively, SDL_KEYUP events can be listened-for. Listening for either event type is suitable.) Any value of SDL_HINT_WINRT_HANDLE_BACK_BUTTON set by such a callback, will be applied to the OS' current back-button-press event. More details on back button behavior in Windows Phone apps can be found at the following page, on Microsoft's developer site: http://msdn.microsoft.com/en-us/library/windowsphone/develop/jj247550(v=vs.105).aspx /

/** \brief Label text for a WinRT app's privacy policy link Network-enabled WinRT apps must include a privacy policy.

SDL provides code to add a link there, with its label text being set via the optional hint, SDL_HINT_WINRT_PRIVACY_POLICY_LABEL. Please note that a privacy policy's contents are not set via this hint. A separate hint, SDL_HINT_WINRT_PRIVACY_POLICY_URL, is used to link to the actual text of the policy. The contents of this hint should be encoded as a UTF8 string. The default value is "Privacy Policy". This hint should only be set during app initialization, preferably before any calls to SDL_Init(). For additional information on linking to a privacy policy, see the documentation for SDL_HINT_WINRT_PRIVACY_POLICY_URL. /

/** \brief A URL to a WinRT app's privacy policy All network-enabled WinRT apps must make a privacy policy available to its users. On Windows 8, 8.1, and RT, Microsoft mandates that this policy be be available in the Windows Settings charm, as accessed from within the app. SDL provides code to add a URL-based link there, which can point to the app's privacy policy. To setup a URL to an app's privacy policy, set SDL_HINT_WINRT_PRIVACY_POLICY_URL before calling any SDL_Init() functions. The contents of the hint should be a valid URL. For example, "http://www.example.com". The default value is "", which will prevent SDL from adding a privacy policy link to the Settings charm. This hint should only be set during app init. The label text of an app's "Privacy Policy" link may be customized via another hint, SDL_HINT_WINRT_PRIVACY_POLICY_LABEL. Please note that on Windows Phone, Microsoft does not provide standard UI for displaying a privacy policy link, and as such, SDL_HINT_WINRT_PRIVACY_POLICY_URL will not get used on that platform. Network-enabled phone apps should display their privacy policy through some other, in-app means. /

\brief A variable that forces X11 windows to create as a custom type. This is currently only used for X11 and ignored elsewhere.

This might be set to various things if SDL_WINDOW_TOOLTIP or SDL_WINDOW_POPUP_MENU, etc, were specified. For "normal" windows that haven't set a specific type, this hint can be used to specify a custom type. For example, a dock window might set this to "_NET_WM_WINDOW_TYPE_DOCK". If not set or set to "", this hint is ignored. This hint must be set before the SDL_CreateWindow() call that it is intended to affect.
