| * NAME |
| * msgctl04.c |
| * |
| * DESCRIPTION |
| * msgctl04 - test for EACCES, EFAULT and EINVAL errors using |
| * a variety of incorrect calls. |
| * |
| * ALGORITHM |
| * create two message queues |
| * loop if that option was specified |
| * try to access a queue with some invalid argument |
| * check the errno value |
| * issue a PASS message if we get EACCES, EFAULT or EINVAL |
| * depending on the test case |
| * otherwise, the tests fails |
| * issue a FAIL message |
| * call cleanup |
| * |
| * USAGE: <for command-line> |
| * msgctl04 [-c n] [-e] [-i n] [-I x] [-P x] [-t] |
| * where, -c n : Run n copies concurrently. |
| * -e : Turn on errno logging. |
| * -i n : Execute test n times. |
| * -I x : Execute test for x seconds. |
| * -P x : Pause for x seconds between iterations. |
| * -t : Turn on syscall timing. |
| * |
| * HISTORY |
| * 03/2001 - Written by Wayne Boyer |
| * 12/03/2008 Matthieu Fertré (Matthieu.Fertre@irisa.fr) |
| * - Fix concurrency issue. The second key used for this test could |
| * conflict with the key from another task. |
| * |
| * RESTRICTIONS |
| * none |
