/*
 * NAME
 * 	close02.c
 *
 * DESCRIPTION
 * 	Check that an invalid file descriptor returns EBADF
 *
 * ALGORITHM
 *	loop if that option is specified
 * 	   call close using the TEST macro and passing in an invalid fd
 *	   if the call succeedes
 *	      issue a FAIL message
 *	   else
 *	      log the errno
 *	      if the errno == EBADF
 *	         issue a PASS message
 *	      else
 *	         issue a FAIL message
 *	cleanup
 *
 * USAGE:  <for command-line>
 *  close02 [-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.
