Note that, unlike the name suggests, there is nothing stream-like
about UDP.
- asr
-
The asynchronous service routine to be called on events such as
datagram arrival without outstanding
Read call. The asr
has a single argument, the event code.
- port
-
A read-only member giving the port number of this UDP Stream.
- Read (timeout)
-
Read a datagram, waiting at most timeout seconds (-1 is
infinite). Return the data.
- Write (host, port, buf)
-
Send buf as a datagram to IP-address host, port
port.
