691 and executing code that you specify on each member of the list.
693 There are two kinds of macros, those requiring surrounding braces, and
694 those not requiring this. Which type of macro will be indicated.
695 The general format for using a brace-requiring macro is
698 LIST_LOOP_3 (elt, list, tail)
705 LIST_LOOP_3 (elt, list, tail)
711 You can put variable declarations between the brace and beginning of
712 macro, but NOTHING ELSE.
714 The brace-requiring macros typically declare themselves any arguments
715 that are initialized and iterated by the macros. If for some reason
716 you need to declare these arguments yourself (e.g. to do something on
717 them before the iteration starts, use the _NO_DECLARE versions of the
721 /* There are two basic kinds of macros: those that handle "internal" lists
722 that are known to be correctly structured (i.e. first element is a cons
723 or nil, and the car of each cons is also a cons or nil, and there are
724 no circularities), and those that handle "external" lists, where the
725 list may have any sort of invalid formation. This is reflected in
726 the names: those with "EXTERNAL_" work with external lists, and those
727 without this prefix work with internal lists. The internal-list
728 macros will hit an assertion failure if the structure is ill-formed;
729 the external-list macros will signal an error in this case, either a
730 malformed-list error or a circular-list error.
732 Note also that the simplest external list iterator, EXTERNAL_LIST_LOOP,
733 does *NOT* check for circularities. Therefore, make sure you call
734 QUIT each iteration or so. However, it's probably easier just to use
735 EXTERNAL_LIST_LOOP_2, which is easier to use in any case.
738 /* LIST_LOOP and EXTERNAL_LIST_LOOP are the simplest macros. They don't
739 require brace surrounding, and iterate through a list, which may or may
740 not known to be syntactically correct. EXTERNAL_LIST_LOOP is for those
741 not known to be correct, and it detects and signals a malformed list
742 error when encountering a problem. Circularities, however, are not
743 handled, and cause looping forever, so make sure to include a QUIT.
744 These functions also accept two args, TAIL (set progressively to each
745 cons starting with the first), and LIST, the list to iterate over.
746 TAIL needs to be defined by the program.
748 In each iteration, you can retrieve the current list item using XCAR
749 (tail), or destructively modify the list using XSETCAR (tail,
752 #define LIST_LOOP(tail, list) \
757 #define EXTERNAL_LIST_LOOP(tail, list) \

767 LIST_LOOP_2 and EXTERNAL_LIST_LOOP_2 are the standard, most-often used
768 macros. They take two arguments, an element variable ELT and the list
769 LIST. ELT is automatically declared, and set to each element in turn
772 LIST_LOOP_3 and EXTERNAL_LIST_LOOP_3 are the same, but they have a third
773 argument TAIL, another automatically-declared variable. At each iteration,
774 this one points to the cons cell for which ELT is the car.
776 EXTERNAL_LIST_LOOP_4 is like EXTERNAL_LIST_LOOP_3 but takes an additional
777 LEN argument, again automatically declared, which counts the number of
778 iterations gone by. It is 0 during the first iteration.
780 EXTERNAL_LIST_LOOP_4_NO_DECLARE is like EXTERNAL_LIST_LOOP_4 but none
781 of the variables are automatically declared, and so you need to declare
782 them yourself. (ELT and TAIL are Lisp_Objects, and LEN is an EMACS_INT.)

995 be a property list, consisting of alternating pairs of keys
996 (typically symbols or keywords) and values. Each iteration
997 processes one such pair out of LIST, assigning the two elements to
998 KEY and VALUE respectively. Malformed lists and circularities are
999 trapped as usual, and in addition, property lists with an odd number

1704 MANY means pass a vector of evaluated arguments,

1707 which contains the argument values.
