/*
 * Test that mq_send() inserts messages into the message queue according
 * to the priority given.  Specifically, test that messages with equal
 * priority values are placed after previously sent messages.
 *
 * Test similar to 3-1.c; however, messages 3 and 4 will have equal priority
 * order, but 3 will be sent first.
 *
 * 3/13/03 - Added fix from Gregoire Pichon for specifying an attr
 *           with a mq_maxmsg >= BUFFER.
