how to specify the IP address and send amessage to Processing

Hi, guys!

I’m using Arduino Yun and I want to send message to Processing
through wifi using by osc library made by CNMAT.

#include <OSCMessage.h>

Make an OSC message and send it over serial

#include <SLIPEncodedUSBSerial.h>
SLIPEncodedUSBSerial SLIPSerial( thisBoardsSerialUSB );
#include <SLIPEncodedSerial.h>
 SLIPEncodedSerial SLIPSerial(Serial1);

void setup() {
  //begin SLIPSerial just like Serial
  SLIPSerial.begin(9600);   // set this as high as you can reliably run on your platform
#if ARDUINO >= 100
    ; //Leonardo "feature"

void loop(){
  //the message wants an OSC address as first argument
  OSCMessage msg("/analog/0");

    msg.send(SLIPSerial); // send the bytes to the SLIP stream
  SLIPSerial.endPacket(); // mark the end of the OSC Packet
  msg.empty(); // free space occupied by message


I want to send a message to Processing using by this sample as a guide , but I do not know how to specify the IP address .How do you send a message by specifying the IP address of the Processing side ?

help me!
