 /*
- * NAME
- *	fchdir01.c
- *
  * DESCRIPTION
  *	fchdir01 - create a directory and cd into it.
- *
- * ALGORITHM
- *	create a new directory
- *	open the directory and get a file descriptor
- *	loop if that option was specified
- *	fchdir() into the directory
- *	check the return code
- *	  if failure, issue a FAIL message.
- *	otherwise,
- *	  if doing functionality testing, call check_functionality()
- *	  	if correct,
- *			issue a PASS message
- *		otherwise
- *			issue a FAIL message
- *	call cleanup
- *
- * USAGE:  <for command-line>
- *  fchdir01 [-c n] [-f] [-i n] [-I x] [-P x] [-t]
- *     where,  -c n : Run n copies concurrently.
- *             -f   : Turn off functionality Testing.
- *	       -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.
- *
- * HISTORY
- *	03/2001 - Written by Wayne Boyer

- * RESTRICTIONS
- *	none
