Also - if you would like, I have a more advanced API for writing libevent based HTTP servers which has built-in thread pool support. At the moment it has only been tested on OSX >= LION, and Linux 2.6.x. You can get the source here: https://github.com/ellzey/libevhtp This API can be used just like a simple libevent http server (but is much more flexible) just like you would with evhttp. If you wanted to create the most simple of http servers with 4 worker threads, the code woud look like this: ---- #include <evhtp.h> static void default_cb(evhtp_request_t * request, void * arg) { evbuffer_add_printf(request->buffer_out, "hi! %s\n", (char *)arg); evhtp_send_reply(req, EVHTP_RES_200); } int main(int argc, char ** argv) { struct event_base * evbase = event_base_new(); evhtp_t * htp = evhtp_new(evbase, NULL); int num_workers = 4; evhtp_set_gencb(htp, default_cb, "foobar"); evhtp_use_threads(htp, num_workers); evhtp_bind_socket(htp, "0.0.0.0", 8080); event_base_loop(evbase, 0); return 0; } ---- A more advanced example can be found here: https://github.com/ellzey/libevhtp/blob/master/test.c *********************************************************************** To unsubscribe, send an e-mail to majord...@freehaven.net with unsubscribe libevent-users in the body.
