Close a Socket Connection

See more Socket/SSL/TLS Examples

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.

func chilkatTest() {
    var success: Bool = false

    let socket = CkoSocket()!

    //  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: Bool = true
    var maxWaitMs: Int = 5000
    success = socket.connect(hostname: "example.com", port: 5000, ssl: bTls, maxWaitMs: maxWaitMs)
    if success == false {
        print("\(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(maxWaitMs: 1000)
    if success == false {
        print("\(socket.lastErrorText!)")
        return
    }

    print("Connection closed.")
