     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 socketcall(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  *
     41  *	Test:
     42  *        Execute system call
     43  *	  Check return code, if system call failed (return=-1)
     44  *	  Log the errno and Issue a FAIL message.
     45  *	  Otherwise, Issue a PASS message.
     46  *
     47  *	Cleanup:
     48  *	  Print errno log and/or timing stats if options given
     49  *
     50  * USAGE:  <for command-line>
     51  *  socketcall04 [-c n] [-e] [-i n] [-I x] [-p x] [-t]
     52  *		where,		-c n : Run n copies concurrently
     53  *				-e   : Turn on errno logging.
     54  *				-h   : Show this help screen
     55  *				-i n : Execute test n times.
     56  *				-I x : Execute test for x seconds.
     57  *				-p   : Pause for SIGUSR1 before starting
     58  *				-P x : Pause for x seconds between iterations.
     59  *				 t   : Turn on syscall timing.
     60  *
     61  * RESTRICTIONS
     62  * None
