| * NAME |
| * fstatat01.c |
| * |
| * DESCRIPTION |
| * This test case will verify basic function of fstatat64/newfstatat |
| * added by kernel 2.6.16 or up. |
| * |
| * USAGE: <for command-line> |
| * fstatat01 [-c n] [-e] [-i n] [-I x] [-P x] [-t] [-p] |
| * where: |
| * -c n : Run n copies simultaneously. |
| * -e : Turn on errno logging. |
| * -i n : Execute test n times. |
| * -I x : Execute test for x seconds. |
| * -p : Pause for SIGUSR1 before starting |
| * -P x : Pause for x seconds between iterations. |
| * -t : Turn on syscall timing. |
