Get the usable desktop area represented by a display.
int SDL_GetDisplayUsableBounds(int displayIndex, SDL_Rect * rect);
the index of the display to query the usable bounds from
the SDL_Rect structure filled in with the display bounds
Returns 0 on success or a negative error code on failure; call SDL_GetError() for more information.
The primary display (
displayIndex zero) is always located at 0,0.
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.
rect is ignored if it is NULL.
This function also returns -1 if the parameter
displayIndex is out of range.
This function is available since SDL 2.0.5.
