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
