Hi,

Hello.

I'm looking for the source code of any existing and running program whitch
makes use of UDP Sockets.
Please could you help me to find some?

I use this to send commands (status and rcon) to Quake 2 servers:

UDP_RECV_TIMEOUT = 3 # seconds

def q2cmd(str)
resp, sock = nil, nil
begin
cmd = "\377\377\377\377#{str}\0"
sock = UDPSocket.open
sock.send(cmd, 0, @server_addr, @server_port)
resp = if select([sock], nil, nil, UDP_RECV_TIMEOUT)
sock.recvfrom(65536)
end
if resp
resp[0] = resp[0][4..-1] # trim quake's leading 0xffffffff
end
rescue IOError, SystemCallError
ensure
sock.close if sock
end
resp
end


Hope this helps,

Regards,

Bill

Yes! Why didn't I remember this select command? :/
Newbies should always relearn Kernel stuff before starting network
programming...
Thank you very much!
