* gvdb_table_walk:
* @table: a #GvdbTable
* @key: a key corresponding to a list
* @open_func: the #GvdbWalkOpenFunc
* @value_func: the #GvdbWalkValueFunc
* @close_func: the #GvdbWalkCloseFunc
* @user_data: data to pass to the callbacks
*
* Looks up the list at @key and iterate over the items in it.
*
* First, @open_func is called to signal that we are starting to iterate over
* the list. Then the list is iterated. When all items in the list have been
* iterated over, the @close_func is called.
*
* When iterating, if a given item in the list is a value then @value_func is
* called.
*
* If a given item in the list is itself a list then @open_func is called. If
* that function returns %TRUE then the walk begins iterating the items in the
* sublist, until there are no more items, at which point a matching
* @close_func call is made. If @open_func returns %FALSE then no iteration of
* the sublist occurs and no corresponding @close_func call is made.
