## foreign-pointer-address

Arguments: fp

Accessor for the non-lisp address within a `foreign-pointer`. setf'able. See make-foreign-pointer.

Note that the non-lisp address accessed by foreign-pointer-address is not stored as a CLOS slot. Instead it is stored in an extra location in the instance which is not touched by the garbage collector. This address can be seen by inspecting the instance with the `:raw t` option. See inspector.htm.

See ftype.htm for information on foreign types in Allegro CL and foreign-functions.htm for general information on foreign functions in Allegro CL.
