Re: [gnet-dev] a few patches and some bugs

[David Helder <dhelder umich edu>]

Ok, I fixed iochannel in HEAD.  I will commit shortly.

I did not update anything else.  That may take some work to fix up.

For example, udp_receive takes a guint-length buffer and returns a gint
representing the number of bytes received or -1 on error.  In Linux,
recvfrom(2)  takes a size_t length buffer and returns an int.  This was
consistent with Linux's recvfrom(2).

However, if the length is greater than 2^31, it returns a negative number
when it succeeds.  This didn't seem right, so I made length a gint.  I
made similar fixes in pack and mcast.

I'm not sure if this is the right thing to do.  Let me know one way or
another.  I can revert the changes.
