Availability:C-language interface function

functor_t PL_new_functor(atom_t name, int arity)

Returns a functor identifier, a handle for the name/arity pair. The returned handle is valid for the entire Prolog session. Future versions may garbage collect functors as part of atom garbage collection. Currently aborts the process with a fatal error on failure. Future versions may raise a resource exception and return (atom_t)0.
