udp-open Udp.open udp namespace-method Udp.open Udp.open(port) -> int Open a socket on a port. 0 Udp open

Opens a non-blocking IPv4 socket bound to port on every interface and returns its handle, or 0 when it could not. Port 0 lets the system pick a free one; Udp.port says which.

  entry {
    let s = Udp.open(port: 0)
    print(s > 0)
