c('PL_get_compound_name

Availability:C-language interface function

int PL_get_compound_name_arity(term_t +t, atom_t *name, size_t *arity)

If t is compound term, the functor name will be assigned over name and the arity over arity (either or both may be NULL). This is the same as PL_get_name_arity(), but this function fails if t is an atom.
