- * NAME
- *	dup201.c
+ * Copyright (c) International Business Machines  Corp., 2001
  *
- * DESCRIPTION
+ * DESCRIPTION:
  *	Negative tests for dup2() with bad fd (EBADF)
  *
- * ALGORITHM
- * 	Setup:
- *	a.	Setup signal handling.
- *	b.	Pause for SIGUSR1 if option specified.
- *
- * 	Test:
- *	a.	Loop if the proper options are given.
- *	b.	Loop through the test cases
- * 	c.	Execute dup2() system call
- *	d.	Check return code, if system call failed (return=-1), test
- *		for EBADF.
- *
- * 	Cleanup:
- * 	a.	Print errno log and/or timing stats if options given
- *
- * USAGE:  <for command-line>
- *  dup201 [-c n] [-e] [-i n] [-I x] [-P x] [-t]
- *     where,  -c n : Run n copies concurrently.
- *             -e   : Turn on errno logging.
- *             -i n : Execute test n times.
- *             -I x : Execute test for x seconds.
- *             -P x : Pause for x seconds between iterations.
- *             -t   : Turn on syscall timing.
- *
- * HISTORY
- *	07/2001 Ported by Wayne Boyer
- *	01/2002 Removed EMFILE test - Paul Larson
- *
- * RESTRICTIONS
- * 	NONE
+ * HISTORY:
+ * 	07/2001 Ported by Wayne Boyer
+ * 	01/2002 Removed EMFILE test - Paul Larson
