Hi,
What does g_hash_table_find() return?
It returns a gpointer, but the api is unclear
on what it is.
Returns: The value of the first key/value pair is returned, for which func
evaluates to TRUE. If no pair with the requested property is found,
NULL is returned.
How can it point to a key *and* its value? I'm trying to get the key
value with little success (it's stored as a guint).
You might want to try g_hash_table_lookup(). You give a key as an argument, and it returns the
associated value. If there's no value identified by the supplied key, it returns NULL.
I have written a small software that makes extensive use of the GHashTable structure:

Hi,
I have used g_hash_table_lookup() ok. However, i'm trying to
do a reverse lookup now where i can supply the value and find
the matching key.
