The function sxhash is a convenient tool for the user
who needs to create more complicated hashed data structures than are
provided by hash-table objects.
[Function]
sxhashobject
sxhash computes a hash code for an object and returns
the hash code as a non-negative fixnum. A property of
sxhash is that
(equalxy)
implies
(= (sxhashx) (sxhashy)).
The manner in which the hash code is computed is
implementation-dependent but independent of the particular
``incarnation’’ or ``core image.’’ Hash values produced by
sxhash may be written out to files, for example, and
meaningfully read in again into an instance of the same
implementation.
