        !             2: Queue Example Description:
        !             3: --------------------------
        !             4: A cafeteria has a headwaiter. He creates a queue into which requests are
        !             5: placed by the cafeteria's gatekeeper.
        !             6: 
        !             7: The cafeteria has a number for each table meant for seating cutomers.
        !             8: The gatekeeper receives customers in groups, assigns each group a table.
        !             9: Corresponding to each table assignment, he places a request (indicating the
        !            10: table at which the customer group is seated) on a queue.
        !            11: When he decides that it is time for closing the cafeteria, he places
        !            12: the last request on the queue indicating that there will be no more
        !            13: customers.
        !            14: 
        !            15: The headwaiter reads each request from the queue (for FIFO : according to
        !            16: first come, first serve. For LIFO, last in gets first table, and for PRIOrity,
        !            17: according to each customers priority) and dispatches a waiter to the table
        !            18: where the customer group is seated.  The headwaiter closes the queue as soon
        !            19: as he reads a request that has the RequestID set to NOMORE (i.e, there will
        !            20: be no more customers).
        !            21: 
        !            22: The file serv.c emulates the headwaiter. The file cust.c emulates
        !            23: the gatekeeper.
        !            24: 
        !            25: Running this example:
        !            26:         The customer and server processes need to be running at the same
        !            27:         time. Hence, do the following:
        !            28: 
        !            29: 
        !            30:                 o At prompt, type
        !            31:                   fifoque <CR>       for FIFO queues example
        !            32:              or   lifoque <CR>       for LIFO queues example
        !            33:              or   prioque <CR>       for PRIOrity queues example
        !            34: 
        !            35: ------------------------------------------------------------------------------
