    Downloading files (not sockets)

    I was wondering how to simply download files on Linux with C++, off the internet. I don't understand sockets too well, but from what I do understand your server needs to have support set up, and you only need sockets for input/output, not just output.


    Thanks.

    curl, make a front-end to wget, yep we got options.
    * PC: Intel Core 2 DUO E6550 @ 2.33 GHz with 2 GB RAM: Archlinux-i686 with xfce4.
    * Laptop: Intel Core 2 DUO T6600 @ 2.20 GHz with 4 GB RAM: Archlinux-x86-64 with xfce4.

    Hmm. Well, most people would consider downloading input. Except that you may want to download something specific, other than random space dust, so that will mean asking for it! Sending a "request", as it were! That will be the "output"!

    In other words, you do need input/output for this. However, this idea that "your server needs to have support set up" is not so well thought out. Consider: you have a web browser, and obviously your web browser is capable of downloading. Does it do this via sockets? Yes! Does it require some kind of special arrangement with "your server" that does not already exist? No!
    C programming resources:
    GNU C Function and Macro Index -- glibc reference manual
    The C Book -- nice online learner guide
    Current ISO draft standard
    CCAN -- new CPAN like open source library repository
    3 (different) GNU debugger tutorials: #1 -- #2 -- #3
    cpwiki -- our wiki on sourceforge

    You don't even have to make a front-end. I think (it has been a while) that one can compile wget as a library and statically link to it.
