I want to transfer files across the network using C or C++. What topics should I look up? How can I do this?

    Not that I feel confident that I'll be able to answer the question anyway, but... this question sounds lacking in detail. – Kache Mar 16 '10 at 06:18
  • Across *what* network? If possible, just create a network share and copy the files across like you would anywhere else. – Jerry Coffin Mar 16 '10 at 06:28

You should start by choosing a protocol. HTTPS and SFTP are both good choices, but there are obviously others. Once you have that straight, you can look up choices for client and server libraries.

  • FTP is insecure, and should be used only inside a firewall, or over a secure layer (e.g. http://en.wikipedia.org/wiki/FTPS) – Matthew Flaschen Mar 16 '10 at 06:25
  • the OP doesn't necessarily need to encrypt the transmitted data. – Bertrand Marron Mar 16 '10 at 07:32

    @tusbar: if you have secure libraries, why not use them? For completeness, there's also scp. libcurl was suggested here: http://stackoverflow.com/questions/360259/sftp-c-library/360276#360276 – stefaanv Mar 17 '10 at 10:06

I would recommend looking through documentation of Windows Sockets and boost asio.

While you could use ReadFile to read the file's contents and then send it over a socket, Windows also provides the TransmitFile API to enable you to read a file's data and send it over a socket with one system call.
