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.

import 'package:chilkat/chilkat.dart';

void main() {
  final socket = CkSocket();

  // Connect to the server using TLS.
  final bTls = true;
  final maxWaitMs = 5000;
  try {
    socket.connect('example.com', 5000, bTls, maxWaitMs);
  } on ChilkatException catch (e) {
    print(e.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.
  final bd = CkBinData();
  try {
    socket.receiveBdN(256, bd);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  print('Received ${bd.numBytes} bytes.');
