When you use URL url = new URL("http://192.168.0.2/myfile.txt"); in Java you actually read the file with the help of HTTP protocol over TCP, to make this in C you need to
1) use sockets (SOCK_STREAM since we are using TCP protocol) to establish connection to the remote server 192.168.0.2 on port 80 (this is default for http protocol)
(see http://beej.us/guide/bgnet/output/htmlsingle/bgnet.html, the great tutorial for sockets programming)
2) you need to send HTTP GET Request to the server over created socket, e.g.
Code:
GET /myfile.txt HTTP/1.0
Host: 192.168.0.2
(see RFC 2616)
3) then you need to parse HTTP Response (if you lucky you just need to remove HTTP header, if not you need to decode base64 encoding, handle HTTP errors etc., all information about what you need to do written in HTTP Response header)
(see RFC 2616)
If you still want to recieve file from remote server in C program try some library for HTTP protocol, you can also use Perl or scp for instance.
