SDL_GetDisplayUsableBounds - Man Page

#include <SDL3/SDL_video.h>

bool SDL_GetDisplayUsableBounds(SDL_DisplayID displayID, SDL_Rect *rect);

This is the same area as SDL_GetDisplayBounds() reports, but with portions reserved by the system removed. For example, on Apple's macOS, 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.

displayID

the instance ID of the display to query.

rect

the SDL_Rect structure filled in with the display bounds.
