ich hab da mal ne Frage zu boost::asio... und zwar... dort gibt es die Klasse boost::asio::tcp::socket und diese hat unter anderem folgende Methoden:

async_read und async_receive

was ist denn genau der unterschied zwischen read und receive? Wann nimmt man was?

Danke schonmal

The receive operation may not receive all of the requested number of bytes. Consider using the async_read function if you need to ensure that the requested amount of data is received before the asynchronous operation completes.

Edit:
Ah, das scheinen die flags zu sein:

/// Peek at incoming data without removing it from the input queue.
  static const int message_peek = implementation_defined;

  /// Process out-of-band data.
  static const int message_out_of_band = implementation_defined;

  /// Specify that the data should not be subject to routing.
  static const int message_do_not_route = implementation_defined;
