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 test is run for option 2 for sysfs(2)
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  * sysfs02  [-c n] [-e] [-i n] [-I x] [-P x] [-t] [-h] [-t] [-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
