21 * NAME
22 *	rmdir01
23 *
24 * DESCRIPTION
25 *	This test will verify that rmdir(2) syscall basic functionality.
26 *	verify rmdir(2) returns a value of 0 and the directory being
27 *	removed
28 *
29 * ALGORITHM
30 *	Setup:
31 *		Setup signal handling.
32 *		Create temporary directory.
33 *		Pause for SIGUSR1 if option specified.
34 *
35 *	Test:
36 *		Loop if the proper options are given.
37 *                 make a directory tstdir
38 *                 call rmdir(tstdir), check the return value
39 *                 verify the directory tstdir does not exists.
40 *
41 *	Cleanup:
42 *		Print errno log and/or timing stats if options given
43 *		Delete the temporary directory created.*
44 * USAGE
45 *	rmdir01 [-c n] [-f] [-i n] [-I x] [-P x] [-t]
46 *	where,  -c n : Run n copies concurrently.
47 *		-f   : Turn off functionality Testing.
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.
