Function sdl2_sys::SDL_GetDisplayUsableBounds

pub unsafe extern "C" fn SDL_GetDisplayUsableBounds(
    displayIndex: c_int, 
    rect: *mut SDL_Rect
) -> c_int

\brief Get the usable desktop area represented by a display, with the primary display located at 0,0

This is the same area as SDL_GetDisplayBounds() reports, but with portions reserved by the system removed. For example, on Mac OS X, 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.

\return 0 on success, or -1 if the index is out of range.
