21 * NAME
22 * fchdir02.c
23 *
24 * DESCRIPTION
25 * fchdir02 - try to cd into a bad directory (bad fd).
26 *
27 * CALLS
28 * fchdir()
29 *
30 * ALGORITHM
31 * loop if that option was specified
32 * call fchdir() with an invalid file descriptor
33 * check the errno value
34 * issue a PASS message if we get EBADF - errno 9
35 * otherwise, the tests fails
36 * issue a FAIL message
37 * break any remaining tests
38 * call cleanup
39 *
40 * USAGE: <for command-line>
41 * fchdir02 [-c n] [-e] [-i n] [-I x] [-P x] [-t]
42 * where, -c n : Run n copies concurrently.
43 * -e : Turn on errno logging.
44 * -i n : Execute test n times.
45 * -I x : Execute test for x seconds.
46 * -P x : Pause for x seconds between iterations.
47 * -t : Turn on syscall timing.
