/*
 * NAME
 *	rename07
 *
 * DESCRIPTION
 *	This test will verify that rename(2) failed in ENOTDIR
 *
 * CALLS
 *	stat,open,rename,mkdir,close
 *
 * ALGORITHM
 *	Setup:
 *		Setup signal handling.
 *		Create temporary directory.
 *		Pause for SIGUSR1 if option specified.
 *              create the "old" directory and the "new" file
 *              rename the "old" directory to the "new" file
 *
 *	Test:
 *		Loop if the proper options are given.
 *                  verify rename() failed and returned ENOTDIR
 *
 *	Cleanup:
 *		Print errno log and/or timing stats if options given
 *		Delete the temporary directory created.*
 * USAGE
 *	rename07 [-c n] [-e] [-i n] [-I x] [-p x] [-t]
 *	where,  -c n : Run n copies concurrently.
 *		-e   : Turn on errno logging.
 *		-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.
