Receive an Exact Number of Bytes into a BinData

See more Socket/SSL/TLS Examples

Demonstrates Socket.ReceiveBdN, which receives exactly the requested number of bytes and appends them to a BinData, continuing until the full count is satisfied.

func chilkatTest() {
    var success: Bool = false

    let socket = CkoSocket()!

    //  Connect to the server using TLS.
    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
    }

    //  MaxReadIdleMs controls the inactivity limit for receiving.  The ReceiveBdN call will fail if
    //  incoming bytes halt for longer than this many milliseconds before the full amount is received.
    socket.maxReadIdleMs = 15000

    //  Receive exactly the requested number of bytes, appending them to a BinData.  The method continues
    //  receiving until the full count is satisfied or a failure occurs.
    let bd = CkoBinData()!
    success = socket.receiveBdN(numBytes: 256, binData: bd)
    if success == false {
        print("\(socket.lastErrorText!)")
        return
    }

    print("Received \(bd.numBytes.intValue) bytes.")
