* 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.
