puthash-key

$Revision: 5.0.2.4 $

Function

Package: EXCL

Arguments: (key hash-table)

As a side effect, may add an entry to a sans values (a key-only) hash table (one created with the values argument to cl:make-hashtable specified nil), if the equivalent key entry is not already in the table. Regardless of whether the given key was added or an equivalent entry is found, puthash-key returns the key that is actually in the hash-table. This allows objects to be kept in a hash-table efficiently without duplication.

See the description of extensions to cl:make-hash-table in 5.5 cl:make-hash-table in implementation.htm.
