- *
- * TEST IDENTIFIER : sched_setparam02
- *
- * EXECUTED BY : root / superuser
- *
- * TEST TITLE : Checks functionality for sched_setparam(2)
- *
- * TEST CASE TOTAL : 1
- *
- * 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
- * This test changes the scheduling priority for current process
- * and verifies it by calling sched_getparam().
- *
- * Setup:
- * Setup signal handling.
- * Pause for SIGUSR1 if option specified.
- * Change scheduling policy to SCHED_FIFO
- *
- * Test:
- * Loop if the proper options are given.
- * Execute system call
- * If scheduling priority is set properly,
- * TEST passed
- * else
- * TEST failed
- *
- * Cleanup:
- * Print errno log and/or timing stats if options given
+
+/*\
+ * [Description]
*
- * USAGE: <for command-line>
- * sched_setparam02 [-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.
+ * Checks functionality for sched_setparam(2)
