19 * TEST IDENTIFIER : reboot01
20 *
21 * EXECUTED BY : root / superuser
22 *
23 * TEST TITLE : Basic test for reboot(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 reboot(2) system call.
35 * It is intended to provide a limited exposure of the system call.
36 * $
37 *
38 * Setup:
39 * Setup signal handling.
40 * Pause for SIGUSR1 if option specified.
41 * setting the flag value for two tests.
42 *
43 * Test:
44 * Loop if the proper options are given.
45 * for two test cases for two flag values
46 * Execute system call
47 * Check return code, if system call failed (return=-1)
48 * Log the errno and Issue a FAIL message.
49 * Otherwise, Issue a PASS message.
50 *
51 * Cleanup:
52 * Print errno log and/or timing stats if options given
53 *
54 * USAGE: <for command-line>
55 * reboot01 [-c n] [-e] [-i n] [-I x] [-p x] [-t] [-h] [-f] [-p]
56 * where:
57 * -c n : run the test for n number of times.
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 *for lib4 and lib5 reboot(2) system call is implemented as
67 *int reboot(int magic, int magic2, int flag, void *arg); This test case
68 *is written for int reboot(int flag); which is implemented under glibc
69 *Therefore this testcase may not work under libc4 and libc5 libraries
