Function SDL_GetCurrentDisplayMode 

pub unsafe extern "C" fn SDL_GetCurrentDisplayMode(
    displayID: SDL_DisplayID,
) -> *const SDL_DisplayMode

Get information about the current display mode.

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.

Parameters

• displayID: the instance ID of the display to query.

Return value

Returns a pointer to the desktop display mode or NULL on failure; call SDL_GetError() for more information.

Thread safety

This function should only be called on the main thread.

Availability

This function is available since SDL 3.2.0.
