note 50350 added to function.proc-open

Is there any chance to use the optional parameters mentioned in the function signature above? There is no documentation about them either. When I try to specify "cwd" I get the following result: PHP Warning: proc_open() expects exactly 3 parameters, 4 given in I:\test_proc.php on line 46 My PHP version (Win32): I:\>php_cli.exe --version PHP 4.3.10 (cli) (built: Dec 14 2004 17:48:04) Copyright (c) 1997-2004 The PHP Group Zend Engine v1.3.0, Copyright (c) 1998-2004 Zend Technologies ---- Manual Page -- http://www.php.net/manual/en/function.proc-open.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+50350 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+50350&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+50350&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+50350&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+50350&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+50350&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+50350&report=yes Search -- http://master.php.net/manage/user-notes.php
