+ * NAME
+ *	msgctl02.c
+ *
+ * DESCRIPTION
+ *	msgctl02 - create a message queue, then issue the IPC_SET command
+ *		   to lower the msg_qbytes value.
+ *
+ * ALGORITHM
+ *	create a message queue
+ *	loop if that option was specified
+ *	call msgctl() with the IPC_SET command with a new msg_qbytes value
+ *	check the return code
+ *	  if failure, issue a FAIL message and break remaining tests
+ *	otherwise,
+ *	  if doing functionality testing
+ *	  	if the msg_qbytes value is the new value
+ *			issue a PASS message
+ *		otherwise
+ *			issue a FAIL message
+ *	  else issue a PASS message
+ *	call cleanup
+ *
+ * USAGE:  <for command-line>
+ *  msgctl02 [-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
