How to include new OPCODE in Guacamole-Client and Guacamole-Server

[Amarjeet Singh]

Hi Team,


How can I add new OPCODE as there is file  and filesystem in Guacamole
Client and Guacamole-Server


GUACAMOLE - CLIENT
{code:none}
"file": function(parameters) {

            var stream_index = parseInt(parameters[0]);
            var mimetype = parameters[1];
            var filename = parameters[2];

            // Create stream
            if (guac_client.onfile) {
                var stream = streams[stream_index] = new
Guacamole.InputStream(guac_client, stream_index);
                guac_client.onfile(stream, mimetype, filename);
            }

            // Otherwise, unsupported
            else
                guac_client.sendAck(stream_index, "File transfer
unsupported", 0x0100);

        },

  "filesystem" : function handleFilesystem(parameters) {

            var objectIndex = parseInt(parameters[0]);
            var name = parameters[1];

            // Create object, if supported
            if (guac_client.onfilesystem) {
                var object = objects[objectIndex] = new
Guacamole.Object(guac_client, objectIndex);
                guac_client.onfilesystem(object, name);
            }

            // If unsupported, simply ignore the availability of the
filesystem

    },
{code}


GUACAMOLE - SERVER
{code:none}
int guac_protocol_send_file(guac_socket* socket, const guac_stream* stream,
        const char* mimetype, const char* name) {

    int ret_val;

    guac_socket_instruction_begin(socket);
    ret_val =
           guac_socket_write_string(socket, "4.file,")
        || __guac_socket_write_length_int(socket, stream->index)
        || guac_socket_write_string(socket, ",")
        || __guac_socket_write_length_string(socket, mimetype)
        || guac_socket_write_string(socket, ",")
        || __guac_socket_write_length_string(socket, name)
        || guac_socket_write_string(socket, ";");

    guac_socket_instruction_end(socket);
    return ret_val;

}

{code}

I can't just change "file" to  another opcode and create another function
without knowing the behaviour of the opcode.


Please advice me how to add any customized opcode and how to handle it.
