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.
