The low-level interface to the Cascade QueueServer (qserve) is normally not used directly by a program. These functions are entirely encapsulated within other functions in this library. They are included here for completeness.
IP_QueueOpen - opens a queue for reading or writing.
IP_QueueClose - closes a queue.
IP_QueueWrite - writes a message to a queue.
IP_QueueRead - reads a message from the queue.
IP_QueueWait - requests notification of an event.
IP_QueueStrerror - gives access to error strings.
