Control connection and data connection for a FTP client question

[ariel_ro]

Hello all you C gurus!
I would like to know if it is necessary to fork a main process in order to create a data connection. In many examples on the internet it is mentioned that the FTP client needs 2 processes to handle the proper transfer of information.

Many thanks for any kind of help!
