* Routine to start semaphore example *
*--------------------------------------------------------------*
* *
* Name: StartSemExample(VOID) *
* *
* Purpose: Calls routines to create semaphores and draw *
* resources. Creates consumer threads. *
* *
* Usage: Called in file usercmd.c when the user selects *
* start from the semaphore menu. *
* *
* Method: Uses routines in paint.c to draw consumers and *
* resources. This is done by creating a paint *
* message, not calling the draw routines directly. *
* *
* Returns: TRUE if start succeeds, FALSE if start fails *
* *
