SDL_DisplayMode* SDL_GetClosestDisplayMode	(	int	displayIndex,
		const SDL_DisplayMode *	mode,
		SDL_DisplayMode *	closest
	)

Get the closest match to the requested display mode.

Parameters

displayIndex	The index of display from which mode should be queried.
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.

Returns: The passed in value closest, or NULL 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 NULL is returned.

Parameters

w	Pointer to variable for storing the width, may be NULL
h	Pointer to variable for storing the height, may be NULL

This may differ from SDL_GetWindowSize if we're rendering to a high-DPI drawable, i.e. the window was created with SDL_WINDOW_ALLOW_HIGHDPI on a platform with high-DPI support (Apple calls this "Retina"), and not disabled by the SDL_HINT_VIDEO_HIGHDPI_DISABLED hint.

int SDL_GL_GetSwapInterval ( void )

Returns: 0 if there is no vertical retrace synchronization, 1 if the buffer swap is synchronized with the vertical retrace, and -1 if late swaps happen immediately instead of waiting for the next retrace. If the system can't determine the swap interval, or there isn't a valid current context, this will return 0 as a safe default.

Parameters

path	The platform dependent OpenGL library name, or NULL to open the default OpenGL library.

Returns: 0 on success, or -1 if the library couldn't be loaded.

This should be done after initializing the video driver, but before creating any OpenGL windows. If no OpenGL library is loaded, the default library will be loaded upon creation of the first OpenGL window.

Note: If you do this, you need to retrieve all of the GL functions used in your program from the dynamic library using SDL_GL_GetProcAddress().

int SDL_GL_SetSwapInterval ( int interval )

Set the swap interval for the current OpenGL context.

Parameters

interval 0 for immediate updates, 1 for updates synchronized with the vertical retrace. If the system supports it, you may specify -1 to allow late swaps to happen immediately instead of waiting for the next retrace.

void SDL_SetWindowBordered	(	SDL_Window *	window,
		SDL_bool	bordered
	)

Set the border state of a window.

This will add or remove the window's SDL_WINDOW_BORDERLESS flag and add or remove the border from the actual window. This is a no-op if the window's border already matches the requested state.

Parameters

window	The window of which to change the border state.
bordered	SDL_FALSE to remove border, SDL_TRUE to add border.

Note: You can't change the border state of a fullscreen window.

	)

Set the gamma ramp for a window.

Parameters

window	The window for which the gamma ramp should be set.
red	The translation table for the red channel, or NULL.
green	The translation table for the green channel, or NULL.
blue	The translation table for the blue channel, or NULL.

Returns: 0 on success, or -1 if gamma ramps are unsupported.

Set the gamma translation table for the red, green, and blue channels of the video hardware. Each table is an array of 256 16-bit quantities, representing a mapping between the input and output for that channel. The input is the index into the array, and the output is the 16-bit gamma value at that index, scaled to the output color precision.
