| /* |
| * NAME |
| * getitimer03.c |
| * |
| * DESCRIPTION |
| * getitimer03 - check that a getitimer() call fails as expected |
| * with an incorrect first argument. |
| * |
| * CALLS |
| * getitimer() |
| * |
| * ALGORITHM |
| * loop if that option was specified |
| * allocate space and set up needed values |
| * issue the system call |
| * check the errno value |
| * issue a PASS message if we get EINVAL |
| * otherwise, the tests fails |
| * issue a FAIL message |
| * break any remaining tests |
| * call cleanup |
| * |
| * USAGE: <for command-line> |
| * getitmer03 [-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. |
| * |
| * USAGE |
| * ./getitimer03 |
| * |
| * HISTORY |

| * RESTRICTIONS |
