- * NAME
- *	msgget01.c
+ * NAME: msgget01.c
  *
  * DESCRIPTION
- *	msgget01 - create a message queue, write a message to it and
- *		   read it back.
- *
- * ALGORITHM
- *	loop if that option was specified
- *	create a message queue
- *	check the return code
- *	  if failure, issue a FAIL message.
- *	otherwise,
- *	  if doing functionality testing by writting a message to the queue,
- *	  reading it back and comparing the two.
- *	  	if the messages are the same,
- *			issue a PASS message
- *		otherwise
- *			issue a FAIL message
- *	call cleanup
- *
- * USAGE:  <for command-line>
- *  msgget01 [-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
+ * create a message queue, write a message to it and
+ * read it back.
  *
- * RESTRICTIONS
- *	none
