- * NAME
- *	sched_getscheduler02.C
- *
- * DESCRIPTION
- *	To check for the errno ESRCH
+/*\
+ * [Description]
  *
- * ALGORITHM
- *	Pass an invalid pid to sched_getscheduler() and test for ESRCH.
- *
- * USAGE:  <for command-line>
- *  sched_getscheduler02 [-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.
- *
- * RESTRICTION
- *	None
+ * Pass an invalid pid to sched_getscheduler() and test for ESRCH.
