To use them, i included the streamsfuncs.h file, with: #include "ext/standard/streamsfuncs.h" The problem is that when I want to compile, i've these errors: /home/samuel/Développement/workspaces/C-Cpp/PHP_5_3/ext/sockets/sockets.c:877: undefined reference to `stream_array_to_fd_set' /home/samuel/Développement/workspaces/C-Cpp/PHP_5_3/ext/sockets/sockets.c:884: undefined reference to `stream_array_to_fd_set' /home/samuel/Développement/workspaces/C-Cpp/PHP_5_3/ext/sockets/sockets.c:891: undefined reference to `stream_array_to_fd_set' /home/samuel/Développement/workspaces/C-Cpp/PHP_5_3/ext/sockets/sockets.c:936: undefined reference to `stream_array_emulate_read_fd_set' /home/samuel/Développement/workspaces/C-Cpp/PHP_5_3/ext/sockets/sockets.c:957: undefined reference to `stream_array_from_fd_set' /home/samuel/Développement/workspaces/C-Cpp/PHP_5_3/ext/sockets/sockets.c:958: undefined reference to `stream_array_from_fd_set' /home/samuel/Développement/workspaces/C-Cpp/PHP_5_3/ext/sockets/sockets.c:959: undefined reference to `stream_array_from_fd_set' How can I do to use them into my module ?

But I see the actual complaint is on ext/sockets/sockets.c:877: undefined reference to `stream_array_to_fd_set'... What exactly did you do? May the source be with you, Best regards, Jess Portnoy Samuel ROZE wrote: > Nobody can help me ?

If I include the ext/standard/streamsfuncs.c file, where functions are created, I've some errors about the duplication of theses stream functions. I think the problem is that the ext/standard/streamsfuncs.c is loaded after the ext/sockets/socket.c and functions are not initialized yet when the socket.c is builded... BUT, it's a wrong idea because when I move my new function into the streamfuncs.c file, there's the same problem !

To > use them, i included the streamsfuncs.h file, with: stream_array_from_fd_set is declared static in streamsfuncs.c and can't be used in other places. You either have to find a wrapper around it, make the streams layer exporting the functions (there mightbe a reason why they are static - didn't look into it) or find another way to implement what you need. johannes
