Is there any way I can use socket.recvmsg to get ancillary data with asyncio backend?

[JingtaoWang1996]

I was trying to get the ancillary data of a socket with asyncio backend, tried to get the socket timestampe as the dns server querytime.
By modifed the source code, I could get the socket, but the error indicated that the fd of that socket already been used by the transport, even if I closed it. Does anyone has any idea about how to get the ancillary data from the socket ? If so, where should I add "socket.recvmsg" in the source code?

Closing this discussion as there is also an issue, and I'll answer the question there.
