fslot-address

Arguments: object &rest slot-names

The arguments to this function are like those of fslot-value, but this function returns a Lisp integer that represents the address of the slot instead of the value in the slot.

It is like fslot-address-typed, but works only for :foreign or :foreign-static-gcobjects. It cannot be open coded by the compiler. Please see the caution in description of fslot-address-typed about using the returned address value.

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