21 * Test Name: getsockopt01
22 *
23 * Test Description:
24 *  Verify that getsockopt() returns the proper errno for various failure cases
25 *
26 * Usage:  <for command-line>
27 *  getsockopt01 [-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.
