19 *    TEST IDENTIFIER	: sysfs03
20 *
21 *    EXECUTED BY	: anyone
22 *
23 *    TEST TITLE	: Basic test for sysfs(2)
24 *
25 *    TEST CASE TOTAL	: 1
26 *
27 *    AUTHOR		: Aniruddha Marathe <aniruddha.marathe@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 sysfs(2) system call.
35 *    It is intended to provide a limited exposure of the system call.
36 *    This testcase tests sysfs(2) for option 3
37 *
38 *	Setup:
39 *	  Setup signal handling.
40 *	  Pause for SIGUSR1 if option specified.
41 *
42 *	Test:
43 *	 Loop if the proper options are given.
44 *	  Execute system call
45 *	  Check return code, if system call failed (return=-1)
46 *		Log the errno and Issue a FAIL message.
47 *	  Otherwise, Issue a PASS message.
48 *
49 *	Cleanup:
50 *	  Print errno log and/or timing stats if options given
51 *
52 * USAGE:  <for command-line>
53 * sysfs03 [-c n] [-e] [-i n] [-I x] [-P x] [-t] [-h] [-p] [-f]
54 * where:
55 *	-c n : Run n copies simultaneously
56 *	-e   : Turn on errno logging.
57 *	-i n : Execute test n times.
58 *	-I x : Execute test for x seconds.
59 *	-p   : Pause for SIGUSR1 before starting
60 *	-P x : Pause for x seconds between iterations.
61 *	-t   : Turn on syscall timing.
62 *
63 *RESTRICTIONS:
64 *There is no glibc or libc support
