Get value of the SO_SNDBUF option for this DatagramSocket , that is the buffer size used by the platform for output on this DatagramSocket .

Usage

From source file:Main.java

public static void main(String args[]) {
    try {/*from   ww w .  j  a va2s . c  o  m*/

        InetAddress ia = InetAddress.getByName("www.java2s.com");

        DatagramSocket ds = new DatagramSocket();

        byte buffer[] = "hello".getBytes();
        DatagramPacket dp = new DatagramPacket(buffer, buffer.length, ia, 80);

        // Send the datagram packet
        ds.send(dp);

        System.out.println(ds.getSendBufferSize());
    } catch (Exception e) {
        e.printStackTrace();
    }
