I want to try out the I/O multiplexer but I am clueless on how to go about working with it. Any help on this (or pointer to the doc location) would be great. Cheers, ChaitanyaHi, I've written a simple HTTP server that uses IOLib. Maybe it can help one figure out how IOLib works or can be used: http://common-lisp.net/~lnostdal/programming/lisp/sw-http/ Basically start by creating a server socket (server.lisp): * make-socket (iolib) * ..and make it non-blocking * set-io-handler (iolib) * set-error-handler (iolib) set-io-handler (iolib) dispatches to the handle-socket-event (sw-http, server.lisp) callback which calls connection-start-reading (sw-http, connection.lisp). connection-start-reading sets up a new callback, connection-handle (sw-http, connection.lisp) by calling set-io-handler (iolib) on the client socket. It also makes sure the client socket is made non-blocking. connection-handle has a (case event ..) form which leads to request-handle (sw-http, request-incoming.lisp) for :read events. Ok, that's basically it with regards to the multiplexing stuff really. This should be familiar stuff quite similar to what's going on in C on a "concept" level. You keep reading until reading would block then make a note of where you are now then return to the event loop (the blocking event-dispatch call/loop in server.lisp) so the next waiting event in line can be served. _______________________________________________ IOLib-devel mailing list IOLib-devel@common-lisp.net http://common-lisp.net/cgi-bin/mailman/listinfo/iolib-devel
