+ * Name: mq_msgqfree
+ *
+ * Description:
+ *   This function deallocates an initialized message queue
+ *   structure.  First, it deallocates all of the queued
+ *   messages in the message Q.  It is assumed that this
+ *   message is fully unlinked and closed so that not thread
+ *   will attempt access it while it is being deleted.
+ *
+ * Inputs:
+ *   msgq - Named essage queue to be freed
+ *
+ * Return Value:
+ *   None
+ *
