19 * TEST IDENTIFIER : timer_create04
20 *
21 * EXECUTED BY : anyone
22 *
23 * TEST TITLE : Test checking for basic error conditions for
24 * timer_create(2)
25 *
26 * TEST CASE TOTAL : 8
27 *
28 * AUTHOR : Aniruddha Marathe <aniruddha.marathe@wipro.com>
29 *
30 * SIGNALS
31 * Uses SIGUSR1 to pause before test if option set.
32 * (See the parse_opts(3) man page).
33 *
34 * DESCRIPTION
35 * This test case check whether timer_create(2) returns appropriate error
36 * value for invalid parameter
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 * For case 7 set event parameter as bad pointer
45 * for case 8 set returned timer ID parameter as bad pointer
46 * Execute system call with invalid parameter
47 * Check return code, if system call fails with errno == expected errno
48 * Issue syscall passed with expected errno
49 * Otherwise, Issue syscall failed to produce expected errno
50 *
51 * Cleanup:
52 * Print errno log and/or timing stats if options given
53 *
54 * USAGE: <for command-line>
55 * timer_create04 [-c n] [-e] [-i n] [-I x] [-P x] [-t] [-p]
56 * where:
57 * -c n : run n copies simultaneously
58 * -e : Turn on errno logging.
59 * -i n : Execute test n times.
60 * -I x : Execute test for x seconds.
61 * -p : Pause for SIGUSR1 before starting
62 * -P x : Pause for x seconds between iterations.
63 * -t : Turn on syscall timing.
64 *
65 * RESTRICTIONS:
66 * None
