* retrieval and dispatch loop that is the top-level control structure
* for the remainder of execution. The loop is terminated when a WM_QUIT
* message is received, at which time this function exits the application
* instance by returning the value passed by PostQuitMessage().
*
* If this function must abort before entering the message loop, it
* returns the conventional value NULL.
