 *	TEST IDENTIFIER	: access03
 *

 *
 *	TEST TITLE	: EFAULT error testing for access(2)
 *
 *	PARENT DOCUMENT	: acstds01
 *
 *	TEST CASE TOTAL	: 8
 *
 *	WALL CLOCK TIME	: 1
 *
 *	CPU TYPES		: ALL
 *
 *	AUTHOR		: Kathy Olmsted
 *
 *	CO-PILOT		: Tom Hampson
 *
 *	DATE STARTED	: 05/13/92
 *
 *	INITIAL RELEASE	: UNICOS 7.0
 *
 *	TEST CASES
 *
 *	access(2) test for errno(s) EFAULT.
 *
 *	INPUT SPECIFICATIONS
 *	The standard options for system call tests are accepted.
 *	(See the parse_opts(3) man page).
 *
 *	DURATION
 *	Terminates - with frequency and infinite modes.
 *
 *	SIGNALS
 *	Uses SIGUSR1 to pause before test if option set.
 *	(See the parse_opts(3) man page).
 *
 *	ENVIRONMENTAL NEEDS
 *	  No run-time environmental needs.
 *
 *	DETAILED DESCRIPTION
 *
 *	Setup:
 *	  Setup signal handling.
 *		Make and change to a temporary directory.
 *	  Pause for SIGUSR1 if option specified.
 *
 *	Test:
 *	 Loop if the proper options are given.
 *	  Execute system call
 *	  Check return code, if system call failed (return=-1)
 *		Log the errno.
 *		If doing functional test
 *			check the errno returned and print result message
 *
 *	Cleanup:
 *	  Print errno log and/or timing stats if options given
 *		Remove the temporary directory and exit.
 *
