make-hash-table

(make-hash-table &key test size)

Creates and returns a new, empty hash table. Keys are compared structurally, as if by equal, so list, string, number, symbol and character keys match by value. The :test keyword is accepted for familiarity but is informational only -- it does not change the comparison -- and :size and other keywords are ignored. Store entries with (setf (gethash key table) value) and read them with gethash.
