- * 	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.

- *    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
- *
