fslot-value

Arguments: object &rest slot-names

This is like fslot-value-typed except it can only be used to access slots from objects with :foreign or :foreign-static-gc allocations, since these are the only objects that are runtime typed.

This function is a lot more convenient to use than fslot-value-typed since the type and allocation needn't be specified, however it can't at present be open coded. Thus for speed critical parts of the program, fslot-value-typed should be used.

When the accessed slot is a primitive type, then the value of the slot is returned. When the accessed slot is a composite type such as a sub-structure or an array, then the address of the sub-structure or array is returned as a Lisp integer. 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.
