/*
 * NAME
 *	rmdir01
 *
 * DESCRIPTION
 *	This test will verify that rmdir(2) syscall basic functionality.
 *	verify rmdir(2) returns a value of 0 and the directory being
 *	removed 
 *
 * ALGORITHM
 *	Setup:
 *		Setup signal handling.
 *		Create temporary directory.
 *		Pause for SIGUSR1 if option specified.
 *
 *	Test:
 *		Loop if the proper options are given.
 *                 make a directory tstdir
 *                 call rmdir(tstdir), check the return value
 *                 verify the directory tstdir does not exists.
 *
 *	Cleanup:
 *		Print errno log and/or timing stats if options given
 *		Delete the temporary directory created.*
 * USAGE
 *	rmdir01 [-c n] [-f] [-i n] [-I x] [-P x] [-t]
 *	where,  -c n : Run n copies concurrently.
 *		-f   : Turn off functionality Testing.
 *		-i n : Execute test n times.
 *		-I x : Execute test for x seconds.
 *		-P x : Pause for x seconds between iterations.
 *		-t   : Turn on syscall timing.
 *
 * HISTORY
 *	07/2001 Ported by Wayne Boyer
 *
 * RESTRICTIONS
 *	None.
