[Chicken-users] udp.scm

[Daishi Kato]

Hi,

I'm very new to the scheme and CHICKEN,
and trying to use udp.scm.

The example code just gives me:

8<------8<------8<------8<------8<------8<------

Version 1, Build 63 - linux-unix-gnu-x86
(c)2000-2004 Felix L. Winkelmann
#;> (require 'udp)
; loading /usr/local/lib/chicken/udp.so ...
#;> (define s (udp-open-socket))
#;> (udp-bind! s #f 0)
#;> (udp-connect! s "localhost" 13)
#;> (udp-send s "\n")
1
#;> (receive (n data from-host from-port) (udp-recvfrom s 64) (print* n " bytes 
from " from-host ":" from-port ": " data))
Error: recvfrom

8<------8<------8<------8<------8<------8<------

Would somebody figure out what is wrong with it?
Any clue to debug this kind of error would also help.

Thanks,
Daishi
