- *  _CORE_message_queue_Flush_support
- *
- *  This message handler routine removes all messages from a message queue
- *  and returns them to the inactive message pool.  The number of messages
- *  flushed from the queue is returned
- *
- *  Input parameters:
- *    the_message_queue - pointer to message queue
- *
- *  Output parameters:
- *    returns - number of messages placed on inactive chain
- *
- *  INTERRUPT LATENCY:
- *    only case

-  /*
-   *  Currently, RTEMS supports no API that has both flush and blocking
-   *  sends.  Thus, this routine assumes that there are no senders
-   *  blocked waiting to send messages.  In the event, that an API is
-   *  added that can flush a message queue when threads are blocked
-   *  waiting to send, there are two basic behaviors envisioned:
-   *
-   *  (1) The thread queue of pending senders is a logical extension
-   *  of the pending message queue.  In this case, it should be 
-   *  flushed using the _Thread_queue_Flush() service with a status
-   *  such as CORE_MESSAGE_QUEUE_SENDER_FLUSHED (which currently does
-   *  not exist).  This can be implemented without changing the "big-O"
-   *  of the message flushing part of the routine.
-   *
-   *  (2) Only the actual messages queued should be purged.  In this case,
-   *  the blocked sender threads must be allowed to send their messages.
-   *  In this case, the implementation will be forced to individually
-   *  dequeue the senders and queue their messages.  This will force
-   *  this routine to have "big O(n)" where n is the number of blocked
-   *  senders.  If there are more messages pending than senders blocked,
-   *  then the existing flush code can be used to dispose of the remaining
-   *  pending messages.
-   *
-   *  For now, though, we are very happy to have a small routine with 
-   *  fixed execution time that only deals with pending messages.
