     21  * NAME
     22  *	fchdir01.c
     23  *
     24  * DESCRIPTION
     25  *	fchdir01 - create a directory and cd into it.
     26  *
     27  * ALGORITHM
     28  *	create a new directory
     29  *	open the directory and get a file descriptor
     30  *	loop if that option was specified
     31  *	fchdir() into the directory
     32  *	check the return code
     33  *	  if failure, issue a FAIL message.
     34  *	otherwise,
     35  *	  if doing functionality testing, call check_functionality()
     36  *	  	if correct,
     37  *			issue a PASS message
     38  *		otherwise
     39  *			issue a FAIL message
     40  *	call cleanup
     41  *
     42  * USAGE:  <for command-line>
     43  *  fchdir01 [-c n] [-f] [-i n] [-I x] [-P x] [-t]
     44  *     where,  -c n : Run n copies concurrently.
     45  *             -f   : Turn off functionality Testing.
     46  *	       -i n : Execute test n times.
     47  *	       -I x : Execute test for x seconds.
     48  *	       -P x : Pause for x seconds between iterations.
     49  *	       -t   : Turn on syscall timing.
