begin_send() [2/3]

xtd::sptr< xtd::iasync_result > xtd::net::sockets::udp_client::begin_send	(	const std::vector< xtd::byte > &	dgram,
		size_t	bytes,
		const xtd::net::ip_end_point &	end_point,
		xtd::async_callback	callback,
		const std::any &	state
	)

xtd::net::sockets::udp_client::sends a datagram to a destination asynchronously. The destination is specified by a EndPoint.

Parameters

dgram	A byte array that contains the data to be sent.
bytes	The number of bytes to send.
end_point	The EndPoint that represents the destination for the data.
callback	An xtd::async_callback delegate that references the method to invoke when the operation is complete.
state	A user-defined object that contains information about the send operation. This object is passed to the callback delegate when the operation is complete.

Returns

An xtd::iasync_result object that references the asynchronous send.

Remarks

The asynchronous xtd::net::sockets::udp_client::begin_send operation must be completed by calling the xtd::net::sockets::udp_client::end_send method. Typically, the method is invoked by the callback delegate.

This method does not block until the operation is complete. To block until the operation is complete, use one of the xtd::net::sockets::udp_client::send method overloads.
