 *    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. 
 *
