KQUEUE Utilization

This is your lame attempt to understand how those Network Virtual Functions sofware works as well to sharpen your understanding on C++ and C programming language.

Hints

• Compile using g++ for the file watcher

To trace the function calls on FreeBSD based system use truss() instead of strace.

The kqueue_socket.c is my attempt on create a socket watcher timer program using kevent.

• KQUEUE NETBSD GUIDE

    struct kevent my_event;
    struct kevent my_change;

    EV_SET(&my_change, ...); // Initialize the kevent

    for(;;){

        ...;

    }

    

Goal

• Understand the difference between c++ and C
• Understand how strcuct works and the difference between it on c++ and C
• Understand

Issues

• Modification to target file only detected after 2 or more interrupt
