19 * TEST IDENTIFIER : socketcall02
20 *
21 * EXECUTED BY : All user
22 *
23 * TEST TITLE : Error test for socketcall(2)
24 *
25 * TEST CASE TOTAL : 1
26 *
27 * AUTHOR : sowmya adiga<sowmya.adiga@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 * verify socketcall(2) returns -1 and sets errno
35 * appropriately if argument passed is invalid.
36 *
37 *
38 * Setup:
39 * Setup signal handling.
40 * Pause for SIGUSR1 if option specified.
41 *
42 * Test:
43 * Loop if the proper option is given.
44 * Execute system call.
45 * Check return code, If system call failed (return == -1) &&
46 * (errno set == expected errno)
47 * Issue sys call pass with expected error
48 * otherwise
49 * Issue sys call fails with unexpected error
50 *
51 * Cleanup:
52 * Print errno log and/or timing stats if options given
53 *
54 * USAGE: <for command-line>
55 * socketcall02 [-c n] [-e] [-i n] [-I x] [-p x] [-t]
56 * where, -c n : Run n copies concurrently
57 * -e : Turn on errno logging.
58 * -h : Show this help screen
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
