get-foreign-type

Arguments: name-or-ftype &optional errorp

Returns an internal structure containing a description of a foreign type. This internal structure can be passed to those functions that take a foreign type name (such as allocate-fobject).

This function is useful when the foreign-type is a type description, such as (:array :int 10), that must be parsed each time it is used in a function such as allocate-fobject. By calling get-foreign-type once on (:array :int 10) to create the internal description, and then passing that internal description each time to allocate-fobject, that will save the parsing cost on each call.

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