 *
 *    TEST IDENTIFIER	: socketcall02
 *
 *    EXECUTED BY	: All user
 *
 *    TEST TITLE	: Error test for socketcall(2)
 *
 *    TEST CASE TOTAL	: 1
 *
 *    AUTHOR		: sowmya adiga<sowmya.adiga@wipro.com>
 *
 *    SIGNALS
 *	Uses SIGUSR1 to pause before test if option set.
 *	(See the parse_opts(3) man page).
 *
 *    DESCRIPTION
 *	verify socketcall(2) returns -1 and sets errno
 *	appropriately if argument passed is invalid.
 *
 *
 *	Setup:
 *	  Setup signal handling.
 *	  Pause for SIGUSR1 if option specified.
 *
 *	Test:
 *	  Loop if the proper option is given.
 *	  Execute system call.
 *	  Check return code, If system call failed (return == -1) &&
 *				(errno set == expected errno)
 *	  Issue sys call pass with expected error
 *	  otherwise
 *	  Issue sys call fails with unexpected error
 *
 *	Cleanup:
 *	  Print errno log and/or timing stats if options given
 *
 * USAGE:  <for command-line>
 *  socketcall02 [-c n] [-e] [-i n] [-I x] [-p x] [-t]
 *		where,		-c n : Run n copies concurrently
 *				-e   : Turn on errno logging.
 *				-h   : Show this help screen
 *				-i n : Execute test n times.
 *				-I x : Execute test for x seconds.
 *				-p   : Pause for SIGUSR1 before starting
 *				-P x : Pause for x seconds between iterations.
 *				-t   : Turn on syscall timing.
 *
 * RESTRICTIONS
 * None
