Subject: Hash tables - how to look up values?
Date: Wed, 04 Jul 2012 15:48:09 +0200 [thread overview]
Message-ID: <873957d4di.fsf@googlemail.com> (raw)
Hi List,
I would need a function that does the opposite of
,--------------------
| (gethash key table)
`--------------------
i.e. something like
,-------------------
| (getkey val table)
`-------------------
that returns the corresponding key of a known (string) value in a hash
table (similar to 'rassoc' for alists).
I could not find such a function - does it exist already?

cheers,
Thorsten
