 *    TEST IDENTIFIER	: ulimit01
 * 
 *    EXECUTED BY	: anyone
 * 
 *    TEST TITLE	: Basic test for ulimit(2)
 * 
 *    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.) ulimit(2) returns...(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 ulimit(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
 *	ulimit(2).
 * 
 * 	Setup:
 * 	  Setup signal handling.
 *	  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 and Issue a FAIL message.
 *	  Otherwise, Issue a PASS message.
 * 
 * 	Cleanup:
 * 	  Print errno log and/or timing stats if options given
 * 
 *
