/*
 * Test Name: socket01
 *
 * Test Description:
 *  Verify that socket() returns the proper errno for various failure cases
 *
 * Usage:  <for command-line>
 *  socket01 [-c n] [-e][-i n] [-I x] [-p x] [-t]
 *	where,  -c n : Run n copies concurrently.
 *		-e   : Turn on errno logging.
 *		-i n : Execute test n times.
 *		-I x : Execute test for x seconds.
 *		-P x : Pause for x seconds between iterations.
 *		-t   : Turn on syscall timing.
 *
 * History
 *	07/2001 John George
 *		-Ported
 *
 * Restrictions:
 *  None.
