/**
* g_vfs_ftp_connection_listen_data_connection:
* @conn: a connection
* @error: %NULL or location to take potential errors
*
* Initiates a listening socket that the FTP server can connect to. To accept
* connections and initialize data transfers, use
* g_vfs_ftp_connection_accept_data_connection().
* This function supports what is known as "active FTP", while
* g_vfs_ftp_connection_open_data_connection() is to be used for "passive FTP".
*
* Returns: the actual address the socket is listening on or %NULL on error
