Close a Socket Connection

Demonstrates Socket.Close, which gracefully terminates and closes the current TCP, TLS, or SSH channel connection. The argument bounds how long to wait for clean shutdown processing.

Background. A value of 0 waits indefinitely for the clean close, while a positive value waits up to that many milliseconds.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

JavaScript

var success = false;

var socket = new CkSocket();

//  Connect to the server using TLS.  The 3rd argument enables the TLS handshake after the TCP
//  connection succeeds; the 4th is the maximum time to wait, in milliseconds.
var bTls = true;
var maxWaitMs = 5000;
success = socket.Connect("example.com",5000,bTls,maxWaitMs);
if (success == false) {
    console.log(socket.LastErrorText);
    return;
}

//  StringCharset controls the character encoding used when sending and receiving text.
socket.StringCharset = "utf-8";

//  Gracefully close the current TCP, TLS, or SSH channel connection.  The argument is the maximum
//  number of milliseconds to wait for clean shutdown processing (0 waits indefinitely).
success = socket.Close(1000);
if (success == false) {
    console.log(socket.LastErrorText);
    return;
}

console.log("Connection closed.");
