SYNOPSIS

       typedef bool (SDLCALL *SDL_WindowsMessageHook)(void *userdata, MSG *msg);

DESCRIPTION

       This  callback  may  modify  the  message,  and  should  return true if the message should continue to be
       processed, or false to prevent further processing.

       As this is processing a message directly from the Windows event loop, this callback should do the minimum
       required work and return quickly.

RETURN VALUE

THREAD SAFETY

       This may only be called (by SDL) from the thread handling the Windows event loop.

AVAILABILITY
