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  *    This test is carried out for option 1 for sysfs(2).
36  *    It is intended to provide a limited exposure of the system call.
37  *
38  *
39  *	Setup:
40  *	  Setup signal handling.
41  *	  Pause for SIGUSR1 if option specified.
42  *
43  *	Test:
44  *	 Loop if the proper options are given.
45  *	  Execute system call
46  *	  Check return code, if system call failed (return=-1)
47  *		Log the errno and Issue a FAIL message.
48  *	  Otherwise, Issue a PASS message.
49  *
50  *	Cleanup:
51  *	  Print errno log and/or timing stats if options given
52  *
53  * USAGE:  <for command-line>
54  * sysfs01 [-c n]  [-e] [-i n] [-I x] [-p x] [-t] [-h] [-f] [-p]
55  *  where:
56  *	-c n : run n copies simultaneously.
57  *	-e   : Turn on errno logging.
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.
63  *
64  *RESTRICTIONS:
65  *There is no glibc or libc support
66  *Kernel should be compiled with proc filesystem support
