- * NAME
- * sched_setscheduler01.c
+/*\
+ * [Description]
*
- * DESCRIPTION
- * Testcase to test whether sched_setscheduler(2) sets the errnos
- * correctly.
+ * Testcase to test whether sched_setscheduler(2) sets the errnos
+ * correctly.
*
- * 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
+ * [Algorithm]
*
- * 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.
- *
- * 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
