/*
 * NAME
 *	sched_getscheduler02.C
 *
 * DESCRIPTION
 *	To check for the errno ESRCH
 *
 * ALGORITHM
 *	Pass an invalid pid to sched_getscheduler() and test for ESRCH.
 *
 * USAGE:  <for command-line>
 *  sched_getscheduler02 [-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.
 *
 * RESTRICTION
 *	None
