Availability:C-language interface function
int PL_predicate_info(predicate_t
p, atom_t *n, size_t *a, module_t *m)Return information on the predicate p. The name is stored
over
n, the arity over a, while m receives
the definition module. Note that the latter need not be the same as
specified with
PL_predicate().
If the predicate is imported into the module given to
PL_predicate(),
this function will return the module where the predicate is defined. Any
of the arguments n, a and m can be
NULL. Currently always returns TRUE.
