|  * NAME
 | |
|  *	sched_setscheduler01.c
 | |
|  *
 | |
|  * DESCRIPTION
 | |
|  *	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
 | |
|  *
 | |
|  * 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.
