java.net.Socket.setSoLinger truncates the linger value on Win32

Name: yyC67448 Date: 06/24/98



The java.net.Socket.setSoLinger(boolean, int) truncates the linger value
to 2-byte integer on Win32 systems.

Here is the test demonstrating the bug:

---------------------------- test.java --------------------------------

import java.net.*;


class test
{

  public static void main(String args[])
  {
    InetAddress sin = null;
    Socket soc = null;
    int linger = 65546;
    int value = 0;


    /*
     * Try to get localhost address
     */
    try {
      sin = InetAddress.getLocalHost();
    } catch(Exception e)
    {
      System.out.println("Can not get localhost Address:" + e);
      System.exit(-1);
    }


    /*
     * Hope Telnet service enabled on localhost
     */
    try {
      soc = new Socket(sin, 23, true);
    } catch(Exception e)
    {
      System.out.println("Can not create socket:" + e);
      System.exit(-1);
    }

    try {
      soc.setSoLinger(true, linger);
      value = soc.getSoLinger();
    }
    catch(Exception e)
    {
      try {
        soc.close();
      } catch(Exception e1)
      {
        System.out.println("Can not close socket :" + e1);
        System.exit(-1);
      }
      System.out.println("Unexpected exception:" + e);
    }

    try {
       soc.close();
    } catch(Exception e1)
    {
      System.out.println("Can not close socket :" + e1);
      System.exit(-1);
    }

    if( value != linger)
    {
      System.out.println("Failed. " + value + " != " + linger);
      System.exit(-1);
    }

    System.out.println("OKAY");
    
  }
}



---------------------- Output from the test -----------------
Failed. 10 != 65546
