Description
I have been trying to use client_sock.peek to pull some data from UDP to determine my packet routing. When I try peek with UDP it appears empty (nil). I have seen documentation around peek with TCP and conversations debating whether or not UDP would work the same. Can you please confirm if peek with UDP should function or not?
