| * NAME |
| * chdir01.c |
| * |
| * DESCRIPTION |
| * Check proper operation of chdir(): tests whether the |
| * system call can it change the current, working directory, and find a |
| * file there? Will it fail on a non-directory entry ? |
| * |
| * ALGORITHM |
| * Make a directory "Testdirectory", and create a file in it. cd into |
| * the directory and read the entry. It should be the file just |
| * created. |
| * |
| * USAGE: <for command-line> |
| * chdir01 [-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 |
| * 07/2001 Ported by Wayne Boyer |
| * |
| * RESTRICTIONS |
| * None |
