/*
 * NAME
 *	mkdir05
 *
 * DESCRIPTION
 *	This test will verify the mkdir(2) syscall basic functionality
 *
 * ALGORITHM
 *	Setup:
 *		Setup signal handling
 *		Pause for SIGUSR1 if option specified
 *		Create temporary directory
 *
 *	Test:
 *		Loop if the proper options are given
 *              call mkdir() using the TEST macro
 *		if the call fails, issue FAIL message and contine
 *		if STD_FUNCTIONAL_TEST
 *		   stat the directory
 *		   check for correct owner and group ID
 *		   if these are correct
 *		      issue a PASS message
 *		   else
 *		      issue a FAIL message
 *              else
 *		   issue a PASS message
 *
 *	Cleanup:
 *		Print errno log and/or timing stats if options given
 *		Delete the temporary directory created
 * USAGE
 *	mkdir05 [-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.
