@cnindex meta_predicate/1 (directive)
Each @var{Gi} is a mode specification.
If the argument is @code{:} or an integer, the argument is a call and
must be expanded. Otherwise, the argument is not expanded. Note
that the system already includes declarations for all built-ins.
If the argument is @code{:}, it does not refer directly to a predicate
but must be module expanded. If the argument is an integer, the argument
is a goal or a closure and must be expanded. Otherwise, the argument is
not expanded. Note that the system already includes declarations for all
built-ins.
For example, the declaration for @code{call/1} and @code{setof/3} are:
@example
:- meta_predicate call(:), setof(?,:,?).
:- meta_predicate call(0), setof(?,0,?).
@end example
@end table
