Poll a Socket for Available Data

See more Socket/SSL/TLS Examples

Demonstrates Socket.PollDataAvailable, which performs a nonblocking check for readable activity and returns whether data or another read-ready condition is present.

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;
  }

  // Perform a nonblocking check for readable data.  Returns true when data or another read-ready
  // condition is present, and false when nothing is immediately available.
  final bAvailable = socket.pollDataAvailable();
  if (!bAvailable) {
    print('No data is immediately available.');
  } else {
    print('Data is available to read.');
  }
