FTP Low level functions
Low level functions allow the user to manage basic FTP functionalities, as creating a socket, or
reading/writing chars on FTP command or data socket. Using this set of command, the user can build
its own functions to access FTP services, but has to manage the timeouts and parse the answers from
the server. In general, the "FTP high level functions" offer an easier and more flexible solution to
manage almost every FTP client functionalities.
Create an FTP client socket → FTPClientOpen(char ftpaddr[],
char ftpport[]);
Creates an FTP client on the specified IP address and port.

char ServerName[]);
Open a PassiveMode data exchange between Flyport (Client) and the Server .

sockpasv: handle of the socket for commands exchange.

Returns:
TCP_SOCKET to use for data transfer in Passive Mode
Close FTP client connection → FTPClose(TCP_SOCKET Sockclose);
