C++: how to upload files using ftp

matiasar · 02-24-2009, 01:55 PM

I'm doing my firsts real life C++ programs... I made a program that process some mysql data and then creates xml files that must be uploaded to a remote ftp host.

I would appreciate very much if some of you could give me some advice on what's the best (and simplest) way to upload files with ftp from a C++ program.
I was thinking about doing some system call and running a bash script that can send the files. Is that a good way?

Thanks in advance,
Matías

You could call the shell and ftp the file, but another option is to use an ftp c++ library to send the file within your C++ code. google c++ ftp library, there are quite a few. libcurl is one that we use, it does ftp and many more.

I don't like calling the shell from my programs, because there are too many unknowns and its more difficult to determine what the problem was and how to recover from it.

No, it isn't. I recommend a good communications library (my favorite is libcurl). cURL (and libcurl) are very simple, stable, and flexible.

Thanks for the info folks!
I'll take a look to libcurl.
