 *    TEST CASES
 *
 * 	1-?.) dup(2) returns -1 with errno set to EBADF...(See Description)
 *
 *    INPUT SPECIFICATIONS
 * 	The standard options for system call tests are accepted.
 *	(See the parse_opts(3) man page).
 *
 *    OUTPUT SPECIFICATIONS
 *	Standard tst_res formatted output
 *$
 *    DURATION
 * 	Terminates - with frequency and infinite modes.
 *
 *    SIGNALS
 * 	Uses SIGUSR1 to pause before test if option set.
 * 	(See the parse_opts(3) man page).

 *
 *    DETAILED DESCRIPTION
 *
 * 	Setup:
 * 	  Setup signal handling.
 *	  Pause for SIGUSR1 if option specified.
 *
 * 	Test:
 *	 Loop if the proper options are given.
 *	  Loop through the test cases
 * 	   Execute system call
 *	   Check return code, if system call failed (return=-1)
 *		if doing functional check
 *		   check if errno set correctly, report results
 *	  Otherwise, Issue a FAIL message.
 *
 * 	Cleanup:
 * 	  Print errno log and/or timing stats if options given
