UPD Logging Server
[1/2] from: rsnell::webtrends::com at: 12-Dec-2000 10:30
I have been using a TCP logging server for some stuff
here at work for a couple of months now. Works fine with
the latest Core experimental. It just waits for line data
from a client and displays it when received (code below).
Now I want to change to UDP instead of TCP. Unfortunately
it doesn't appear to be just a simple change of protocol since
I'm getting error messages when trying to use first and pick
on the port. And more unfortunately, there is little UDP documentation
from RT (at least that I can find).
Here is the TCP version - what do I need to do for a UDP version?
REBOL []
sp: open/lines/no-wait/with tcp://:5599 form newline
forever [
cp: first wait sp
d: "none"
forever [
w: wait [cp .1]
if all [port? w none? d][
;connection closed - wait for a new one and continue
cp: first wait sp
d: "none"
]
if port? w [
print d: pick cp 1
]
]
]
Thanks,
Rodney

Change
sp: open/lines/no-wait/with tcp://:5599 form newline
to
sp: open/direct/no-wait udp://:5599
and do all port i/o directly on the main port (sp). UDP does not
create subports for each incoming packet, i.e. you do not need
the "cp: first wait sp" any more.
