Function

Package: FOREIGN-FUNCTIONS

Arguments: (ftype)

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

If type is a symbol defined using def-foreign-type, then the definition form is returned. If type is one of the primitive foreign type symbols or is a list in the form valid for def-foreign-type, then type itself is returned. If type 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.
