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.
