- * NAME
- *	sched_setscheduler01.c
- *
- * DESCRIPTION
- *	Testcase to test whether sched_setscheduler(2) sets the errnos
- *	correctly.
+/*\
+ * [Description]
  *
- * ALGORITHM
- *	1.	Call sched_setscheduler with an invalid pid, and expect
- *	ESRCH to be returned.
- *	2.	Call sched_setscheduler with an invalid scheduling policy,
- *	and expect EINVAL to be returned.
- *	3.	Call sched_setscheduler with an invalid "param" address,
- *	which lies outside the address space of the process, and expect
- *	EFAULT to be returned.
- *	4.	Call sched_setscheduler with an invalid priority value
- *	in "param" and expect EINVAL to be returned
+ * Testcase to test whether sched_setscheduler(2) sets the errnos
+ * correctly.
  *
- * USAGE:  <for command-line>
- *  sched_setscheduler01 [-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.
+ * [Algorithm]
  *
- * HISTORY
- *	07/2001 Ported by Wayne Boyer
- *
- * RESTRICTIONS
- *	None
+ * 1. Call sched_setscheduler with an invalid pid, and expect
+ * ESRCH to be returned.
+ * 2. Call sched_setscheduler with an invalid scheduling policy,
+ * and expect EINVAL to be returned.
+ * 3. Call sched_setscheduler with an invalid "param" address,
+ * which lies outside the address space of the process, and expect
+ * EFAULT to be returned.
+ * 4.Call sched_setscheduler with an invalid priority value
+ * in "param" and expect EINVAL to be returned
