Check Whether a Socket Is Writable

See more Socket/SSL/TLS Examples

Demonstrates Socket.CheckWriteable, which waits for the connected socket to become writable. It returns 1 if writable, 0 if it did not become writable before the timeout, or -1 on error.

    success := false

    socket := chilkat.NewSocket()

    //  Connect to the server using TLS.
    bTls := true
    maxWaitMs := 5000
    success = socket.Connect("example.com",5000,bTls,maxWaitMs)
    if success == false {
        fmt.Println(socket.LastErrorText())
        socket.DisposeSocket()
        return
    }

    //  Wait up to 5 seconds for the socket to become writable.  Returns 1 if writable, 0 if it did not
    //  become writable before the timeout, or -1 on error.
    writable := socket.CheckWriteable(5000)
    if writable < 0 {
        fmt.Println(socket.LastErrorText())
        socket.DisposeSocket()
        return
    }

    if writable != 1 {
        fmt.Println("The socket did not become writable before the timeout.")
        socket.DisposeSocket()
        return
    }

    fmt.Println("The socket is writable.")
