To connect to remote FTP server, the user application calls HsFtpCliConnect, supplying connection parameters, such as remote FTP server name or IP address, username and password for authentication etc and a pointer to callback function that the HS FTP module uses to communicate with the user code.
When the control FTP connection is established and HS FTP has successfully passed user / password FTP account authentication phase, the user application is asynchronously notified via user event callback function with HS_FTPCLI_USR_EV_LOGGEDIN event. The user application can now request remote FTP server directory listing using HsFtpCliList function, change directory HsFtpCliChdir, transfer files with HsFtpCliSendFile and HsFtpCliGetFile.
