| 21 | * NAME |
| 22 | * fchdir01.c |
| 23 | * |
| 24 | * DESCRIPTION |
| 25 | * fchdir01 - create a directory and cd into it. |
| 26 | * |
| 27 | * ALGORITHM |
| 28 | * create a new directory |
| 29 | * open the directory and get a file descriptor |
| 30 | * loop if that option was specified |
| 31 | * fchdir() into the directory |
| 32 | * check the return code |
| 33 | * if failure, issue a FAIL message. |
| 34 | * otherwise, |
| 35 | * if doing functionality testing, call check_functionality() |
| 36 | * if correct, |
| 37 | * issue a PASS message |
| 38 | * otherwise |
| 39 | * issue a FAIL message |
| 40 | * call cleanup |
| 41 | * |
| 42 | * USAGE: <for command-line> |
| 43 | * fchdir01 [-c n] [-f] [-i n] [-I x] [-P x] [-t] |
| 44 | * where, -c n : Run n copies concurrently. |
| 45 | * -f : Turn off functionality Testing. |
| 46 | * -i n : Execute test n times. |
| 47 | * -I x : Execute test for x seconds. |
| 48 | * -P x : Pause for x seconds between iterations. |
| 49 | * -t : Turn on syscall timing. |
