GIOChannel reference counting

["Richard Warren" <rew primagraphics co uk>]

Dear all,

I would be grateful if anyone could tell me whether I need to unreference a 
GIOChannel in order to destroy it properly.

Here's what I'm currently doing:

1. I create a channel with g_io_channel_unix_new() from a socket.  The docs 
state that the initial reference count will be 1.
2. I then add a watch on it with g_io_add_watch().
3. At a later date, I remove the watch with g_source_remove().
4. I want to destroy the channel and free all resources, so call 
g_io_channel_shutdown().

However, the docs for the shutdown function state that the channel will not 
be freed until the last reference is dropped using g_io_channel_unref(). 
Does this include the initial reference added on creation, or is that 
unreferenced by the shutdown function.

I.e., do I need to call g_io_channel_unref() myself to ensure things are 
really freed?

Thanks for any advice you can offer,
Richard.
