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

757 (tail), or destructively modify the list using XSETCAR (tail,

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

1003 be a property list, consisting of alternating pairs of keys
1004 (typically symbols or keywords) and values. Each iteration

1712 MANY means pass a vector of evaluated arguments,
1713 in the form of an integer number-of-arguments
1714 followed by the address of a vector of Lisp_Objects
1715 which contains the argument values.
1716 UNEVALLED means pass the list of unevaluated arguments.
1717 `prompt' says how to read arguments for an interactive call.
