Receive Bytes up to a Delimiter into a BinData

Demonstrates Socket.ReceiveUntilByteBd, which reads bytes until a delimiter byte is encountered and appends all bytes up to and including the delimiter to a BinData.

Background. The delimiter is a raw byte value from 0 through 255. This is useful for framing schemes that terminate each message with a known delimiter byte.

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;
}

//  Read bytes until the delimiter byte is encountered, appending all bytes up to and including the
//  delimiter to a BinData.  The delimiter is a raw byte value from 0 through 255 (here the linefeed
//  byte, decimal 10).
var bd = new CkBinData();
success = socket.ReceiveUntilByteBd(10,bd);
if (success == false) {
    console.log(socket.LastErrorText);
    return;
}

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