23 *
24 *    TEST TITLE	: Test checking for basic error conditions
25 *				 for sysfs(2)
26 *
27 *    TEST CASE TOTAL	: 1
28 *
29 *    AUTHOR		: Aniruddha Marathe <aniruddha.marathe@wipro.com>
30 *
31 *    SIGNALS
32 *	Uses SIGUSR1 to pause before test if option set.
33 *	(See the parse_opts(3) man page).
34 *
35 *    DESCRIPTION
36 *	This test case checks whether sysfs(2) system call  returns
37 *	appropriate error number for invalid
38 *	option.
39 *
40 *	Setup:
41 *	  Setup signal handling.
42 *	  Pause for SIGUSR1 if option specified.
43 *
44 *	Test:
45 *	  Loop if the proper options are given.
46 *	  Execute system call with invaid  option parameter
47 *
48 *	  Check return code, if system call fails with errno == expected errno
49 *		Issue syscall passed with expected errno
50 *	  Otherwise,
51 *	  Issue syscall failed to produce expected errno
52 *
53 *	Cleanup:
54 *	  Do cleanup for the test.
55 *
56 * USAGE:  <for command-line>
57 * sysfs04  [-c n] [-e] [-i n] [-I x] [-P x] [-t] [-h] [-f] [-p]
58 * where:
59 *	-c n : run n copies simultaneously
60 *	-e   : Turn on errno logging.
61 *	-i n : Execute test n times.
62 *	-I x : Execute test for x seconds.
63 *	-p   : Pause for SIGUSR1 before starting
64 *	-P x : Pause for x seconds between iterations.
65 *	-t   : Turn on syscall timing.
66 *
67 *RESTRICTIONS:
68 *No libc or glibc support
