19 * TEST IDENTIFIER : setdomainname01
20 *
21 * EXECUTED BY : root / superuser
22 *
23 * TEST TITLE : Basic test for setdomainame(2)
24 *
25 * TEST CASE TOTAL : 1
26 *
27 * AUTHOR : Saji Kumar.V.R <saji.kumar@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 setdomainname(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 * Save the current domainname.
41 *
42 * Test:
43 * Loop if the proper options are given.
44 * Execute system call
45 * Check return code, if system call failed (return=-1)
46 * Log the errno and Issue a FAIL message.
47 * Otherwise, Issue a PASS message.
48 *
49 * Cleanup:
50 * Restore old domain name.
51 * Print errno log and/or timing stats if options given
52 *
53 * USAGE: <for command-line>
54 * setdomainname01 [-c n] [-e] [-i n] [-I x] [-P x] [-t] [-h] [-f] [-p]
55 * where, -c n : Run n copies concurrently.
56 * -e : Turn on errno logging.
57 * -h : Show help screen
58 * -f : Turn off functional testing
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.
