Call-time pass-by-reference ??

Hello, I am trying to start a small php ncurses app but the documenatation is not helping. What does the following mean: PHP Warning: Call-time pass-by-reference has been deprecated - argument passed by value; If you would like to pass it by reference, modify the declaration of ncurses_getmaxyx(). If you would like to enable call-time pass-by-reference, you can set allow_call_time_pass_reference to true in your INI file. However, future versions may not support this any longer. in /home/michael/gsmenu/gsmenu on line 10 Here is my code: #!/usr/local/bin/php <?php $y=0; $x=0; $ncurses_session = ncurses_init(); $main = ncurses_newwin(0,0,0,0); ncurses_getmaxyx (&$main,$y,$x ); ncurses_border(1,1,1,1, 1,1,1,1); ncurses_wrefresh($main); ncurses_end(); ?> If I remove the "&" from main nothing happens at all, the php documentation says that the variables should be passed from reference. Any help would be appreciated. Michael.
