No, to remove the watch, you return FALSE in the callback function, as
explained here:

I did have a similar problem, I found that I was being notified that there
was input ready to read (via the g_io_channel_add_watch() callback) and was
reading the input, and that was fine.  In some instances (during early the
stages of development) I was trying to read MORE than was waiting for me on
the socket.  This mean't that the read function was waiting for more input
and the rest of the application stopped dealing with events until such time.

If you want me to send you the TCP module I wrote (under Linux), let me
know.

Also, just out of interest, have you thought about using gnet instead?? - I
moved over to it for cross-platform compatibility, it makes light work of
sockets and is fairly straight forward to use:
