SDL_GetCurrentDisplayMode

Get information about the current display mode.

Syntax

int SDL_GetCurrentDisplayMode(int displayIndex, SDL_DisplayMode * mode);

Function Parameters

displayIndex

the index of the display to query

mode

an SDL_DisplayMode structure filled in with the current display mode

Return Value

Returns 0 on success or a negative error code on failure; call SDL_GetError() for more information.

Remarks

There's a difference between this function and SDL_GetDesktopDisplayMode() when SDL runs fullscreen and has changed the resolution. In that case this function will return the current display mode, and not the previous native display mode.

Version

This function is available since SDL 2.0.0.

SDL_GetDesktopDisplayMode
