| * NAME |
| * creat07.c |
| * |
| * DESCRIPTION |
| * Testcase to check creat(2) sets the following errnos correctly: |
| * 1. ETXTBSY |
| * |
| * ALGORITHM |
| * 1. Attempt to creat(2) an executable which is currently running, |
| * and test for ETXTBSY |
| * |
| * USAGE: <for command-line> |
| * creat07 -F test1 [-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. |
| * -F <test file> : Specify the test executable to launch |
| * |
| * HISTORY |
| * 07/2001 Ported by Wayne Boyer |
| * |
| * RESTRICTIONS |
| * test must be run with the -F option |
