questions 'bout snack module...

[¼­Áö¿ø]

I get to know record/play with snack module,

but what I wanna do is get sound data and send it through network in
real-time...

how can i do that?..(should I use Thread or something?..) plz give me brief
example...

p.s) oh, I think I must use UDP instead of TCP/IP

but when I use SOCK_DGRAM instead of SOCK_STREAM, I get "socket error"

when the sock listens...

if possible, plz give me UDP socket program example also... :)
