[Chicken-users] Re: udp.scm

[Daishi Kato]

I made a small change:

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

--- udp.scm.orig        2004-03-25 05:03:46.000000000 +0900
+++ udp.scm     2005-04-03 09:23:15.000000000 +0900
@@ -284,7 +284,7 @@
              (##sys#thread-block-for-i/o! ##sys#current-thread fd i/o)
              (yield)
              (restart-nonblocking name fd i/o thunk))
-            (else (##net#error name))))))
+            (else (##net#error name errno))))))
 
 
 ;;; io:event-dispatch : slist timeout-secs timeout-usecs -> bool

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

which got me know the error is "Connection refused".
I don't know why the connection is refused
and am not sure if this is udp.scm related problem.

There also seems some problems in the non-blocking operation,
but I don't think it has something to do with
the "Connection refused" problem.

Any other help would be appreciated.
