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.
