multicast_loopback() [1/2]

bool xtd::net::sockets::udp_client::multicast_loopback

(

)

const

Gets a boolean value that specifies whether outgoing multicast packets are delivered to the sending application.

Returns

true if the xtd::net::sockets::udp_client receives outgoing multicast packets; otherwise, false.

Exceptions

xtd::net::sockets::socket_exception	An error occurred when attempting to access the underlying socket.
xtd::object_closed_exception	The underlying xtd::net::sockets::socket has been closed.

Remarks

Multicast is a scalable method for many-to-many communication on the Internet. If a process subscribes to a multicast address, any packets sent by that process are received by every other process that has subscribed to the multicast 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.
