end_receive_message_from()

size_t xtd::net::sockets::socket::end_receive_message_from	(	xtd::sptr< xtd::iasync_result >	async_result,
		xtd::net::sockets::socket_flags &	socket_flags,
		xtd::sptr< xtd::net::end_point > &	end_point,
		xtd::net::sockets::ip_packet_information &	ip_packet_information
	)

Ends a pending asynchronous read from a specific endpoint. This method also reveals more information about the packet than xtd::net::sockets::socket::end_receive_from(xtd::iasync_result, xtd::net::end_point).

Parameters

async_result	An xtd::iasync_result that stores state information for this asynchronous operation as well as any user defined data.
socket_flags	A bitwise combination of the xtd::net::sockets::socket_flags values for the received packet.
end_point	The source xtd::net::end_point.
ip_packet_information	The xtd::net::ip_address and interface of the received packet.

Returns

If successful, the number of bytes received. If unsuccessful, returns 0.

Exceptions

argument_exception	asyncResult was not returned by a call to the xtd::net::sockets::socket::begin_receive_message_from method.
xtd::net::sockets::socket_exception	An error occurred when attempting to access the socket.
xtd::object_closed_exception	The xtd::net::sockets::socket has been closed.

Remarks

If the operation has not completed, this method blocks until it does.

To perform this operation synchronously, use the xtd::net::sockets::socket::receive_message_from method.

Examine ipPacketInformation if you need to know if the datagram was sent using a unicast, multicast, or broadcast address.

Note

If you receive a xtd::net::sockets::socket_exception, use the xtd::net::sockets::socket_exception::error_code property to obtain the specific error code. After you have obtained this code, refer to the Windows Sockets version 2 API error code documentation in the MSDN library for a detailed description of the error.
