|  * NAME
 | |
|  *	dup201.c
 | |
|  *
 | |
|  * 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
