# 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](https://wiki.netbsd.org/tutorials/kqueue_tutorial/)

```

    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
