21  * Test Name: bind01
22  *
23  * Test Description:
24  *  Verify that bind() returns the proper errno for various failure cases
25  *
26  * Usage:  <for command-line>
27  *  bind01 [-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.
