Get the numeric ID of a window.


Uint32 SDL_GetWindowID(SDL_Window * window);

Function Parameters

window the window to query

Return Value

Returns the ID of the window on success or 0 on failure; call SDL_GetError() for more information.


The numeric ID is what SDL_WindowEvent references, and is necessary to map these events to specific SDL_Window objects.


This function is available since SDL 2.0.0.
