| * NAME |
| * setuid03.c |
| * |
| * DESCRIPTION |
| * Test to check the error and trivial conditions in setuid |
| * |
| * USAGE: <for command-line> |
| * setuid03 [-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 |
