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

LIST_LOOP_2 and EXTERNAL_LIST_LOOP_2 are the standard, most-often used

LIST. ELT is automatically declared, and set to each element in turn
from LIST.
LIST_LOOP_3 and EXTERNAL_LIST_LOOP_3 are the same, but they have a third
argument TAIL, another automatically-declared variable. At each iteration,
this one points to the cons cell for which ELT is the car.
EXTERNAL_LIST_LOOP_4 is like EXTERNAL_LIST_LOOP_3 but takes an additional
LEN argument, again automatically declared, which counts the number of
iterations gone by. It is 0 during the first iteration.
EXTERNAL_LIST_LOOP_4_NO_DECLARE is like EXTERNAL_LIST_LOOP_4 but none
of the variables are automatically declared, and so you need to declare
them yourself. (ELT and TAIL are Lisp_Objects, and LEN is an EMACS_INT.)

EXTERNAL_ALIST_LOOP_4 is similar to EXTERNAL_LIST_LOOP_2, but it
assumes the elements are aconses (the elements in an alist) and
sets two additional argument variables ELT_CAR and ELT_CDR to the
car and cdr of the acons. All of the variables ELT, ELT_CAR and
ELT_CDR are automatically declared.
EXTERNAL_ALIST_LOOP_5 adds a TAIL argument to EXTERNAL_ALIST_LOOP_4,

declared.
EXTERNAL_ALIST_LOOP_6 adds a LEN argument to EXTERNAL_ALIST_LOOP_5,
just like EXTERNAL_LIST_LOOP_4 does, and again LEN is automatically
declared.
EXTERNAL_ALIST_LOOP_6_NO_DECLARE does not declare any of its arguments,
just like EXTERNAL_LIST_LOOP_4_NO_DECLARE, and so these must be declared
manually.

EXTERNAL_PROPERTY_LIST_LOOP_3 maps over an external list assumed to
be a property list, consisting of alternating pairs of keys
(typically symbols or keywords) and values. Each iteration
processes one such pair out of LIST, assigning the two elements to
KEY and VALUE respectively. Malformed lists and circularities are
trapped as usual, and in addition, property lists with an odd number
of elements also signal an error.
EXTERNAL_PROPERTY_LIST_LOOP_4 adds a TAIL argument to
EXTERNAL_PROPERTY_LIST_LOOP_3, just like EXTERNAL_LIST_LOOP_3 does,
and again TAIL is automatically declared.
EXTERNAL_PROPERTY_LIST_LOOP_5 adds a LEN argument to
EXTERNAL_PROPERTY_LIST_LOOP_4, just like EXTERNAL_LIST_LOOP_4 does,
and again LEN is automatically declared. Note that in this case,
LEN counts the iterations, NOT the total number of list elements
processed, which is 2 * LEN.

/* DEFUN - Define a built-in Lisp-visible C function or `subr'.
`lname' should be the name to give the function in Lisp,
as a null-terminated C string.
`Fname' should be the C equivalent of `lname', using only characters
valid in a C identifier, with an "F" prepended.
The name of the C constant structure that records information
on this function for internal use is "S" concatenated with Fname.
`min_args' should be a number, the minimum number of arguments allowed.
`max_args' should be a number, the maximum number of arguments allowed,
or else MANY or UNEVALLED.
MANY means pass a vector of evaluated arguments,
in the form of an integer number-of-arguments
followed by the address of a vector of Lisp_Objects
which contains the argument values.
UNEVALLED means pass the list of unevaluated arguments.
`prompt' says how to read arguments for an interactive call.
See the doc string for `interactive'.
A null string means call interactively with no arguments.
`arglist' are the comma-separated arguments (always Lisp_Objects) for
the function.
The docstring for the function is placed as a "C" comment between
the prompt and the `args' argument. make-docfile reads the
comment and creates the DOC file from it.

dynamic arrays, there is both MALLOC_OVERHEAD and DYNARR_OVERHEAD

malloc(), malloc() allocates memory beyond what it was asked
