Unrevised from 8.1 to 8.2.
8.1 version

canonical-ftype

Arguments: ftype

If ftype is or names a foreign type, return the symbol or list that describes that type, otherwise return nil.

If ftype is a symbol defined using def-foreign-type, then the definition form is returned. If ftype is one of the primitive foreign type symbols or is a list in the form valid for def-foreign-type, then ftype itself is returned. If ftype is a symbol that has been given a foreign type definition through def-foreign-type, then the foreign definition is returned. Using canonical-ftype allows a quick determination of whether a symbol names a simple type or a structured type.

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