19 * TEST IDENTIFIER : sysfs(2)
20 *
21 *
22 * EXECUTED BY : anyone
23 *
24 * TEST TITLE : Test checking for basic error conditions
25 * for sysfs(2)
26 *
27 * TEST CASE TOTAL : 3
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 and for invalid filesystem name.
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 and for
47 * invalid filesystem name
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 * sysfs05 [-c n] [-e] [-i n] [-I x] [-P x] [-t] [-f] [-h] [-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 *There is no libc or glibc support
69 *Kernel must be compiled with ext2 support
