     97  *	 Loop if the proper options are given.
     98  *	  Loop through the test cases
     99  * 	   Execute system call
    100  *	   Check return code, if system call failed (return=-1)
    101  *		if doing functional check
    102  *		   check if errno set correctly, report results
    103  *	  Otherwise, Issue a FAIL message.
    104  *
    105  * 	Cleanup:
    106  * 	  Print errno log and/or timing stats if options given
