Synchronization Using an Event Semaphore (Part 1)

int cdecl thread()
{
    ulResult = DosCreateEventSem("\SEM32\THREAD", /* Name of semaphore  */
                                 hSem,            /* Semaphore handle   */
                                 NULL,            /* Not used           */
                                 FALSE);          /* Set immediately    */

    <Perform lengthy processing task>

    usResult = DosPostEventSem(hSem);             /* Release semaphore  */
    DosExit(0);                                   /* Terminate thread   */
}

This example shows the routine executing in the secondary thread.
