19 * TEST IDENTIFIER : clock_gettime03
20 *
21 * EXECUTED BY : anyone
22 *
23 * TEST TITLE : Test checking for basic error conditions for
24 * clock_gettime(2)
25 *
26 * TEST CASE TOTAL : 7
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 clock_gettime(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 * If it is the first test case
45 * make temp a bad pointer
46 * Otherwise pass defined struct timespec variable to temp
47 * Execute system call with invalid parameter
48 * Check return code, if system call fails with errno == expected errno
49 * Issue syscall passed with expected errno
50 * Otherwise, Issue syscall failed to produce expected errno
51 *
52 * Cleanup:
53 * Print errno log and/or timing stats if options given
54 *
55 * USAGE: <for command-line>
56 * clock_gettime03 [-c n] [-e] [-i n] [-I x] [-P x] [-t] [-p]
57 * where:
58 * -c n : run n copies simultaneously
59 * -e : Turn on errno logging.
60 * -i n : Execute test n times.
61 * -I x : Execute test for x seconds.
62 * -p : Pause for SIGUSR1 before starting
63 * -P x : Pause for x seconds between iterations.
64 * -t : Turn on syscall timing.
65 *
66 * RESTRICTIONS:
67 * None
