Receive Bytes into a BinData

Demonstrates Socket.ReceiveBd, which receives one delivery of binary data and appends it to a BinData. It returns whatever is immediately available.

Background. The BinData receive methods accumulate raw bytes in a BinData object. A single receive returns only what is currently available, whereas the counted receive waits for an exact number of bytes.

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.
var bTls = true;
var maxWaitMs = 5000;
success = socket.Connect("example.com",5000,bTls,maxWaitMs);
if (success == false) {
    console.log(socket.LastErrorText);
    return;
}

//  Receive one delivery of binary data and append it to a BinData.  ReceiveBd returns whatever is
//  immediately available; it does not loop to drain everything that may follow.
var bd = new CkBinData();
success = socket.ReceiveBd(bd);
if (success == false) {
    console.log(socket.LastErrorText);
    return;
}

console.log("Received " + bd.NumBytes + " bytes.");
