     21  * NAME
     22  * 	close02.c
     23  *
     24  * DESCRIPTION
     25  * 	Check that an invalid file descriptor returns EBADF
     26  *
     27  * ALGORITHM
     28  *	loop if that option is specified
     29  * 	   call close using the TEST macro and passing in an invalid fd
     30  *	   if the call succeedes
     31  *	      issue a FAIL message
     32  *	   else
     33  *	      log the errno
     34  *	      if the errno == EBADF
     35  *	         issue a PASS message
     36  *	      else
     37  *	         issue a FAIL message
     38  *	cleanup
     39  *
     40  * USAGE:  <for command-line>
     41  *  close02 [-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.
