import { Socket } from "https://dotland.deno.dev/std@0.177.0/node/dgram.ts";
Instructs the kernel to leave a source-specific multicast channel at the
given sourceAddress and groupAddress using the
IP_DROP_SOURCE_MEMBERSHIP socket option. This method is automatically
called by the kernel when the socket is closed or the process terminates,
so most apps will never have reason to call this.
If multicastInterface is not specified, the operating system will
attempt to drop membership on all valid interfaces.
