21 * NAME
22 *	rename06
23 *
24 * DESCRIPTION
25 *	This test will verify that rename(2) failed in EINVAL
26 *
27 * ALGORITHM
28 *	Setup:
29 *		Setup signal handling.
30 *		Create temporary directory.
31 *		Pause for SIGUSR1 if option specified.
32 *              create the "old" directory
33 *              create the "new" directory under the "old" directory
34 *
35 *	Test:
36 *		Loop if the proper options are given.
37 *                  rename the "old" to the "new" directory
38 *                  verify rename() failed and returned EINVAL
39 *
40 *	Cleanup:
41 *		Print errno log and/or timing stats if options given
42 *		Delete the temporary directory created.
43 *
44 * USAGE
45 *	rename06 [-c n] [-e] [-i n] [-I x] [-P x] [-t]
46 *	where,  -c n : Run n copies concurrently.
47 *		-e   : Turn on errno logging.
48 *		-i n : Execute test n times.
49 *		-I x : Execute test for x seconds.
50 *		-P x : Pause for x seconds between iterations.
51 *		-t   : Turn on syscall timing.
52 *
53 * HISTORY
54 *	07/2001 Ported by Wayne Boyer
55 *
56 * RESTRICTIONS
57 *	None.
