In the net API (https://nodejs.org/api/net.html) Node allows the reception of an existing socket via its file descriptor - in the server.listen(handle[, backlog][, callback]) API. This is, among other things, useful when receiving the listening socket from a supervising daemon.

Unfortunately no such possibility appears to exist for the dgram API (https://nodejs.org/api/dgram.html).

This is a request to add such a feature in the future.
Thanks.

I think that would be an acceptable change. Pull requests welcome, the libuv function you are looking for is called uv_udp_open(); uv_tcp_open() is its net module counterpart.
