 * NAME
 | 
						|
 *	fchdir02.c
 | 
						|
 *
 | 
						|
 * DESCRIPTION
 | 
						|
 *	fchdir02 - try to cd into a bad directory (bad fd).
 | 
						|
 *
 | 
						|
 * CALLS
 | 
						|
 *	fchdir()
 | 
						|
 *
 | 
						|
 * ALGORITHM
 | 
						|
 *	loop if that option was specified
 | 
						|
 *	call fchdir() with an invalid file descriptor
 | 
						|
 *	check the errno value
 | 
						|
 *	  issue a PASS message if we get EBADF - errno 9
 | 
						|
 *	otherwise, the tests fails
 | 
						|
 *	  issue a FAIL message
 | 
						|
 *	  break any remaining tests
 | 
						|
 *	  call cleanup
 | 
						|
 *
 | 
						|
 * USAGE:  <for command-line>
 | 
						|
 *  fchdir02 [-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.
