C++ (Cpp) socket::receive_from Examples

Example #1

File: dht_server.cpp Project: svn2github/libtorrent-rasterbar

	void thread_fun()
	{
		char buffer[2000];
	
		for (;;)
		{
			error_code ec;
			udp::endpoint from;
			int bytes_transferred = m_socket.receive_from(
				asio::buffer(buffer, sizeof(buffer)), from, 0, ec);
			if (ec == boost::asio::error::operation_aborted
				|| ec == boost::asio::error::bad_descriptor) return;

			if (ec)
			{
				fprintf(stderr, "Error receiving on DHT socket: %s\n", ec.message().c_str());
				return;
			}

			try
			{
				entry msg = bdecode(buffer, buffer + bytes_transferred);

#if defined TORRENT_DEBUG && TORRENT_USE_IOSTREAM
				std::cerr << msg << std::endl;
#endif
				++m_dht_requests;
			}
			catch (std::exception& e)
			{
				fprintf(stderr, "failed to decode DHT message: %s\n", e.what());
			}
