c-way.cpp

This is a simple example illustrating the usage with C-like callback functions.

#include <eventxx>
#include <iostream>
#include <csignal>
 
eventxx::dispatcher d;
 
void sighandler(int signum, short event, void* data)
{
        unsigned &i = *(unsigned*)data;
        std::cout << ++i << " interrupts, ";
        if (i < 5) std::cout << "keep going...\n";
        else
        {
                std::cout << "done!\n";
                d.exit();
        }
}
 
int main()
{
        int var = 0;
        eventxx::csignal sigev(SIGINT, sighandler, &var);
        d.add(sigev);
        d.dispatch();
        return 0;
}
