21 * NAME
22 * sched_getscheduler02.C
23 *
24 * DESCRIPTION
25 * To check for the errno ESRCH
26 *
27 * ALGORITHM
28 * Pass an invalid pid to sched_getscheduler() and test for ESRCH.
29 *
30 * USAGE: <for command-line>
31 * sched_getscheduler02 [-c n] [-e] [-i n] [-I x] [-P x] [-t]
32 * where, -c n : Run n copies concurrently.
33 * -e : Turn on errno logging.
34 * -i n : Execute test n times.
35 * -I x : Execute test for x seconds.
36 * -P x : Pause for x seconds between iterations.
37 * -t : Turn on syscall timing.
38 *
39 * RESTRICTION
40 * None
