libevent-graphite - asynchronous non-blocking Graphite client

=============================================================

Based around libevent bufferevents and designed to be used as part of a bigger

libevent-based application.

Example usage:

    #include 

    

    #include "graphite.h"

    

    void

    connect_cb(struct graphite_connection *c, void *arg)

    {

            struct event *ev = (struct event *)arg;

            struct timeval tv = { 60, 0 };

    

            printf("Connected\n");

    

            evtimer_add(ev, &tv);

    }

    

    void

    disconnect_cb(struct graphite_connection *c, void *arg)

    {

            struct event *ev = (struct event *)arg;

    

            printf("Disconnected\n");

    

            evtimer_del(ev);

    }

    

    void

    timer(int fd, short event, void *arg)

    {

            struct graphite_connection *c = (struct graphite_connection *)arg;

            struct timeval tv;

    

            gettimeofday(&tv, NULL);

    

            graphite_send(c, "universe.answer", "42", tv.tv_sec);

    }

    

    int

    main(int argc, char *argv[])

    {

            struct event_base *base;

            struct timeval tv = { 10, 0 };

            struct graphite_connection *c;

            struct event *ev;

    

            base = event_base_new();

    

            if (graphite_init(base) < 0)

                    return (-1);

    

            if ((c = graphite_connection_new("192.0.2.1",

                GRAPHITE_DEFAULT_PORT, tv)) == NULL)

                    return (-1);

    

            ev = event_new(base, -1, EV_PERSIST, timer, (void *)c);

    

            graphite_connection_setcb(c, connect_cb, disconnect_cb,

                (void *)ev);

    

            graphite_connect(c);

    

            event_base_dispatch(base);

    

            return (0);

    }
