GLib Hash Table "traversal"

[GMail]

Hello,

This is just a shot in the dark, but here goes.  If you are not  
already aware, I am changing the conversations list data structure  
(implemented with a glib List) with the glib Hash Table for a class  
project.  The majority of the functions that use the conversations  
list iterate through it and call various functions based on the value  
at each node of the list.  I have looked at the API for the glib Hash  
Table, but am not sure of the best way to implement a similar  
action.  If you are familiar with glib and/or have any suggestions,  
they would be greatly appreciated.

Thanks in advance and in response to your help with my project.

Regards,
Mike
