21 * Test Name: socketpair01
22 *
23 * Test Description:
24 *  Verify that socketpair() returns the proper errno for various failure cases
25 *
26 * Usage:  <for command-line>
27 *  socketpair01 [-c n] [-e] [-i n] [-I x] [-p x] [-t]
28 *	where,  -c n : Run n copies concurrently.
29 *		-e   : Turn on errno logging.
30 *		-i n : Execute test n times.
31 *		-I x : Execute test for x seconds.
32 *		-P x : Pause for x seconds between iterations.
33 *		-t   : Turn on syscall timing.
34 *
35 * History
36 *	07/2001 John George
