     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.
