Re: Re: Gtk::input_add() for a popen() filehandle?

Is any of this going to work with php4.2? or will it only work with streams (I couldnt see why not - but I could have missed something) regards alan Andrei Zmievski wrote:

Okay, my previous patch was right and the reader function will keep getting called indefinitely until you use gtk::input_remove() so the proper way to do it is: <? dl('php_gtk.so'); function reader($source, $condition) { global $fd; if ($data = fgets($source, 200)) {

       print $data;

} else {

       gtk::input_remove($fd);
       gtk::main_quit();

} } $fp = fopen("config.m4", "r"); $fd = gtk::input_add($fp, GDK_INPUT_READ, 'reader'); gtk::main(); fclose($fp); ?> -Andrei * Only 19,999 lines of C++ to my next ski trip... *
