- *
- *    EXECUTED BY       : anyone
- *
- *    TEST TITLE        : testing error conditions for sched_getparam(2)
- *
- *    TEST CASE TOTAL   : 3
- *
- *    AUTHOR            : Saji Kumar.V.R <saji.kumar@wipro.com>
- *
- *    SIGNALS
- *      Uses SIGUSR1 to pause before test if option set.
- *      (See the parse_opts(3) man page).
- *
- * DESCRIPTION
- * 	Verify that,
- *   1) sched_getparam(2) returns -1 and sets errno to ESRCH if the
- *	process with specified pid could not be found
- *   2) sched_getparam(2) returns -1 and sets errno to EINVAL if
- *	the parameter pid is an invalid value (-1)
- *   3) sched_getparam(2) returns -1 and sets errno to EINVAL if the
- *	parameter p is an invalid address
- *
- * ALGORITHM
- * Setup:
- *   Setup signal handling.
- *   Pause for SIGUSR1 if option specified.
- *
- *  Test:
- *   Loop if the proper options are given.
- *   Execute system call
- *   Check return code, if (system call failed (return=-1)) &
- *			   (errno set == expected errno)
- *              Issue sys call fails with expected return value and errno.
- *   Otherwise,
- *      Issue sys call returns unexpected value.
- *
- *  Cleanup:
- *        Print errno log and/or timing stats if options given

  *
- * USAGE:  <for command-line>
- *  sched_getparam03 [-c n] [-e] [-i n] [-I x] [-P x] [-t] [-h] [-f] [-p]
- *		where,  -c n : Run n copies concurrently.
- *			-e   : Turn on errno logging.
- *			-h   : Show help screen
- *			-f   : Turn off functional testing
- *			-i n : Execute test n times.
- *			-I x : Execute test for x seconds.
- *			-p   : Pause for SIGUSR1 before starting
- *			-P x : Pause for x seconds between iterations.
- *			-t   : Turn on syscall timing.
