Syntax: string ftp_0000ype (int ftp_stream); return value: string function type: Network System Description: This function displays the remote FTP server system, it is equivalent to the system or syst command on the FTP server. The ftp_stream parameter is the FTP connection code. If the call succeeds, a string is returned, for example, "215 UNIX Type: L8". if the call fails, a false value is returned. Ftp_pasvSwitch the active/passive transmission mode. Syntax: boolean ftp_0000ype (int ftp_stream); return value: boolean function type: Network System Description: This function can be switched to active or passive transmission mode, it is equivalent to the passive or pass command under the FTP server.
