int
SP_cons_functor(SP_term_ref term,
SP_atom name,
int arity,
SP_term_ref arg, ...);
Assigns to term a reference to a compound term whose
arguments are the values of arg.... If arity is 0,
assigns the Prolog atom whose canonical representation is
name. This is similar to calling =../2
with the first argument unbound and the second argument bound.
Zero if the conversion fails (as far as failure can be detected), and a nonzero value otherwise.
