I need to work with Ftp, so after looking for various libraries, I accidentally like the MSVC library in codeproject and write down how to create an Ftp client using this library. Instead, I chose to compile and use it with GCC. I modified the errors and the warnings in a somewhat old fashion, not to say what the code itself is.
The original source code from codeproject -- source site
Note: I compiled and built for Windows, but I haven't compiled and built on Unix or Linux yet. It can be run enough on a Unix or Linux system. You can try cross compiling by referring to the Definements.h file.
