23 *    TEST TITLE	: Basic test for sched_get_priority_min(2)
24 *
25 *    TEST CASE TOTAL	: 3
26 *
27 *    AUTHOR		: Saji Kumar.V.R <saji.kumar@wipro.com>
28 *
29 *    SIGNALS
30 * 	Uses SIGUSR1 to pause before test if option set.
31 * 	(See the parse_opts(3) man page).
32 *
33 *    DESCRIPTION
34 *	This is a Phase I test for the sched_get_priority_min(2) system call.
35 *	It is intended to provide a limited exposure of the system call.
36 *
37 * 	Setup:
38 * 	  Setup signal handling.
39 *	  Pause for SIGUSR1 if option specified.
40 *
41 * 	Test:
42 *	 Loop if the proper options are given.
43 * 	  Execute system call
44 *	  Check return code, if system call failed (return=-1)
45 *		Log the errno and Issue a FAIL message.
46 *	  Otherwise, Issue a PASS message.
47 *
48 * 	Cleanup:
49 * 	  Print errno log and/or timing stats if options given
50 *
51 * USAGE:  <for command-line>
52 *  sched_get_priority_min01 [-c n] [-e] [-i n] [-I x] [-P x] [-t] [-h] [-f]
53 * 			     [-p]
54 *			where,  -c n : Run n copies concurrently.
55 *				-e   : Turn on errno logging.
56 *				-h   : Show help screen
57 *				-f   : Turn off functional testing
58 *				-i n : Execute test n times.
59 *				-I x : Execute test for x seconds.
60 *				-p   : Pause for SIGUSR1 before starting
61 *				-P x : Pause for x seconds between iterations.
62 *				-t   : Turn on syscall timing.
