+ *    TEST CASES
+ * 
+ * 	1.) link(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
+ *      No run-time environmental needs.

+ *    INTERCASE DEPENDENCIES
+ * 	None
+ * 
+ *    DETAILED DESCRIPTION
+ *	This is a Phase I test for the link(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
+ *	link(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
+ *
