19 * TEST IDENTIFIER : clock_gettime02
20 *
21 * EXECUTED BY : anyone
22 *
23 * TEST TITLE : Basic test for clock_gettime(2)
24 *
25 * TEST CASE TOTAL : 2
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 clock_gettime(2) system call.
35 * It is intended to provide a limited exposure of the system call.
36 *
37 * Setup:
38 * Setup signal handling.
39 * Pause for SIGUSR1 if option specified.
40 *
41 * Test:
42 * Loop if the proper options are given.
43 * Execute system call for each defined clock value
44 * Check return code, if system call failed (return=-1)
45 * Log the errno and Issue a FAIL message.
46 * Otherwise, Issue a PASS message.
47 *
48 * Cleanup:
49 * Print errno log and/or timing stats if options given
50 *
51 * USAGE: <for command-line>
52 * clock_gettime02 [-c n] [-e] [-i n] [-I x] [-P x] [-t] [-p]
53 * where:
54 * -c n : Run n copies simultaneously.
55 * -e : Turn on errno logging.
56 * -i n : Execute test n times.
57 * -I x : Execute test for x seconds.
58 * -p : Pause for SIGUSR1 before starting
59 * -P x : Pause for x seconds between iterations.
60 * -t : Turn on syscall timing.
61 *
62 *RESTRICTIONS:
63 * None
