This is a simple example illustrating the usage with an arbitrary member function as an event handler callbacks.

#include <eventxx>
#include <iostream>
#include <csignal>
 
using eventxx::dispatcher;
 
struct handler
{
        dispatcher& d;
        int i;
        handler(dispatcher& d): d(d), i(0) {}
        void handle_event(int signum, eventxx::type event)
        {
                std::cout << ++i << " interrupts, ";
                if (i < 5) std::cout << "keep going...\n";
                else
                {
                        std::cout << "done!\n";
                        d.exit();
                }
        }
};
 
typedef eventxx::mem_cb< handler, void (handler::*)(int, eventxx::type) > cb_type;
 
int main()
{
        dispatcher d;
        handler h(d);
        cb_type cb(h, &handler::handle_event);
        eventxx::signal< cb_type > e(SIGINT, cb);
        d.add(e);
        d.dispatch();
        return 0;
}
