Header File

Syntax

SDL_DisplayMode ** SDL_GetFullscreenDisplayModes(SDL_DisplayID displayID, int *count);

Function Parameters

SDL_DisplayID	displayID	the instance ID of the display to query.
int *	count	a pointer filled in with the number of display modes returned, may be NULL.

Return Value

(SDL_DisplayMode **) Returns a NULL terminated array of display mode pointers or NULL on failure; call SDL_GetError() for more information. This is a single allocation that should be freed with SDL_free() when it is no longer needed.

Remarks

The display modes are sorted in this priority:

w -> largest to smallest
h -> largest to smallest
bits per pixel -> more colors to fewer colors
packed pixel layout -> largest to smallest
refresh rate -> highest to lowest
pixel density -> lowest to highest
