| * NAME |
| * uname03.c |
| * |
| * DESCRIPTION |
| * uname03 - call uname() and make sure it succeeds |
| * |
| * ALGORITHM |
| * loop if that option was specified |
| * issue the system call |
| * check the errno value |
| * issue a PASS message if we get zero |
| * otherwise, the tests fails |
| * issue a FAIL message |
| * break any remaining tests |
| * call cleanup |
| * |
| * USAGE: <for command-line> |
| * uname03 [-c n] [-f] [-i n] [-I x] [-p x] [-t] |
| * where, -c n : Run n copies concurrently. |
| * -f : Turn off functionality Testing. |
| * -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 |
| * 07/2001 John George |
| * -Ported |

| * Restrictions |
| * none |
