 *
 *	OS Test - Silicon Graphics, Inc.
 *
 *	TEST IDENTIFIER	: access01
 *
 *	EXECUTED BY	: anyone
 *
 *	TEST TITLE	: Basic test for access(2) using F_OK,
 *						R_OK, W_OK and X_OK arguments.
 *
 *	PARENT DOCUMENT	: usctpl01
 *
 *	TEST CASE TOTAL	: 6
 *
 *	WALL CLOCK TIME	: 1
 *
 *	CPU TYPES		: ALL
 *
 *	AUTHOR		: William Roske
 *
 *	CO-PILOT		: Dave Fenner
 *
 *	DATE STARTED	: 03/30/92
 *
 *	INITIAL RELEASE	: UNICOS 7.0
 *
 *	TEST CASES
 *
 *	1.) access(2) returns 0 for F_OK...(See Description)
 *	2.) access(2) returns 0 for R_OK...(See Description)
 *	3.) access(2) returns 0 for W_OK...(See Description)
 *	4.) access(2) returns 0 for X_OK...(See Description)
 *
 *	INPUT SPECIFICATIONS
 *	The standard options for system call tests are accepted.
 *	(See the parse_opts(3) man page).
 *
 *	OUTPUT SPECIFICATIONS
 *
 *	DURATION
 *	Terminates - with frequency and infinite modes.
 *
 *	SIGNALS
 *	Uses SIGUSR1 to pause before test if option set.
 *	(See the parse_opts(3) man page).
 *
 *	RESOURCES
 *	None
 *
 *	ENVIRONMENTAL NEEDS
 *	The libcuts.a and libsys.a libraries must be included in
 *	the compilation of this test.
 *
 *	SPECIAL PROCEDURAL REQUIREMENTS
 *	None
 *
 *	INTERCASE DEPENDENCIES
 *	None
 *
 *	DETAILED DESCRIPTION
 *	This is a Phase I test for the access(2) system call.  It is intended
 *	to provide a limited exposure of the system call, for now.  It
 *	should/will be extended when full functional tests are written for
 *	access(2).
 *
 *	Setup:
 *	  Setup signal handling.
 *	  Pause for SIGUSR1 if option specified.
 *	  Create a temp directory and cd to it.
 *	  Creat a temp file wil read, write and execute permissions.
 *
 *	Test:
 *	 Loop if the proper options are given.
 *	  Execute system call with F_OK on tmp file
 *	  Check return code, if system call failed (return=-1)
 *		Log the errno and Issue a FAIL message.
 *	  Otherwise, Issue a PASS message.
 *	  Execute system call with X_OK on tmp file...
 *	  Execute system call with W_OK on tmp file...
 *	  Execute system call with R_OK on tmp file...
 *
 *	Cleanup:
 *	  Print errno log
 *
