[Boost-users] pcap_loop callback with boost::function and boost::bind

Hi, I am writing a statistical protocol analyzer running under Windows with WinPcap. The problem is: The pcap_loop function for starting to capture the packets wants a C style callback function, but I need that callback function to have access to several class variables, so this callback function should be a member function. I know that it is not possible to use a member function directly, because of the additional parameter, the pointer to the class. I thought, maybe I could use boost::function and boost::bind, but I am not sure if my solution is correct, so it would be very nice if some of you guys could just look over it and tell me if this is a good way to do this. This is my code for starting the capture: void MyClass::startCapturing() { boost::function < void (u_char *, const struct pcap_pkthdr *, const u_char *) > f; f = boost::bind(&MyClass::packetHandler, this, _1, _2, _3); pcap_handler p = *(f.target()); pcap_loop(hnd, 0, p, NULL); } This the callback function I want pcap_loop to call: void MyClass::packetHandler(u_char *param, const struct pcap_pkthdr *header, const u_char *pkt_data) { /* Do something with the packet.. */ } And this is the signature of the callback argument in the pcap_loop function, as defined in pcap.h: typedef void(*) pcap_handler(u_char *param, const struct pcap_pkthdr *pkt_header, const u_char *pkt_data) If you have an alternative, I would be glad to hear it! Maybe there's a much simpler solution, I didn't think about. Best regards, Clemens
