| * Test that if O_NONBLOCK is set and the message queue is full, mq_timedsend() |
| * will just return an error message and the message will not be queued. |
| * |
| * Test by sending messages with increasing priority number until a failure |
| * is received. Then test that the message just sent (highest priority) is |
| * not the one received. |
| * |
| * 3/13/03 - Added fix from Gregoire Pichon for specifying an attr |
| * with a mq_msgsize >= BUFFER. |
