| * NAME |
| * fchdir01.c |
| * |
| * DESCRIPTION |
| * fchdir01 - create a directory and cd into it. |
| * |
| * ALGORITHM |
| * create a new directory |
| * open the directory and get a file descriptor |
| * loop if that option was specified |
| * fchdir() into the directory |
| * check the return code |
| * if failure, issue a FAIL message. |
| * otherwise, |
| * if doing functionality testing, call check_functionality() |
| * if correct, |
| * issue a PASS message |
| * otherwise |
| * issue a FAIL message |
| * call cleanup |
| * |
| * USAGE: <for command-line> |
| * fchdir01 [-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 |
| * 03/2001 - Written by Wayne Boyer |
