maplist(+Pred, +List)

   Succeeds if Pred(Elem) succeeds for every element of List.



Arguments
   +Pred               Atom or compound term.
   +List               List.

Type
   library(lists)

Description
   maplist/3 succeeds if for every element of List, the invocation of
   Pred with one aditional argument which is this element succeeds.

   The definition of this Prolog library predicate is:

:- tool(maplist/2, maplist_body/3).

maplist_body(_, [], _).
maplist_body(Pred, [Head|Tail], Module) :-
    call(Pred, Head)@Module,
    maplist_body(Pred, Tail, Module).

   This predicate does not perform any type testing functions.
	

Modules
   This predicate is sensitive to its module context (tool predicate, see @/2).

Fail Conditions
   Fails if at least for one element of List the invocation of Pred with this additional argument fails.

Resatisfiable
   Resatisfiable if at least for one element of List the invocation of Pred with this additional argument is resatisfiable.

Examples
   
Success:
  maplist(integer, [1, 3, 5]).
  maplist(spy, [var/1, functor/3]).

Fail:
  maplist(current_op(_, _), [+, -, =]).
  (fails because the precedence of = does not match that of +)
