In XEmacs, the use of `char' and `char *' is almost always a
mistake. If you want to manipulate an Emacs character from "C",
use `Emchar'. If you want to examine a specific octet in the
pointer to move through the internal text, use `Bufbyte *'. Also
note that you almost certainly do not need `Emchar *'.

its text properties. The value is always `nil'.
This is convenient because it lets the user use all the kill
commands to copy text into the kill ring from a read-only buffer.

appropriate. It also invokes the value of
`interprogram-cut-function' (see below).
- - Function: kill-append STRING BEFORE-P

An image specifier is used to describe the actual image of a glyph.
-It works like other specifiers (*note Specifiers::.), in that it
-contains a number of specifications describing how the image should
-appear in a variety of circumstances. These specifications are called
-"image instantiators". When XEmacs wants to display the image, it
-instantiates the image into an "image instance". Image instances are
-their own primitive object type (similar to font instances and color
-instances), describing how the image appears in a particular domain.
-(On the other hand, image instantiators, which are just descriptions of
-how the image should appear, are represented using strings or vectors.)

The Predicates for Characters
=============================
- - Function: characterp OBJECT
+ - Function: characterp object
This function returns `t' if OBJECT is a character.
Some functions that work on integers (e.g. the comparison functions
in the future; therefore, do not rely on them. Instead, convert
the characters explicitly using `char-int'.
- - Function: integer-or-char-p OBJECT
+ - Function: integer-or-char-p object
This function returns `t' if OBJECT is an integer or character.
\1f
Character Codes
===============
- - Function: char-int CH
+ - Function: char-int ch
This function converts a character into an equivalent integer.
The resulting integer will always be non-negative. The integers in
the range 0 - 255 map to characters as follows:
XEmacs, the order in which character sets were loaded, etc., and
you should not depend on them.
- - Function: int-char INTEGER
+ - Function: int-char integer
This function converts an integer into the equivalent character.
Not all integers correspond to valid characters; use `char-int-p'
to determine whether this is the case. If the integer cannot be
converted, `nil' is returned.
- - Function: char-int-p OBJECT
+ - Function: char-int-p object
This function returns `t' if OBJECT is an integer that can be
converted into a character.
- - Function: char-or-char-int-p OBJECT
+ - Function: char-or-char-int-p object
This function returns `t' if OBJECT is a character or an integer
that can be converted into one.
Comparison of Characters and Strings
====================================
- - Function: char-equal CHARACTER1 CHARACTER2
+ - Function: char-equal character1 character2
This function returns `t' if the arguments represent the same
character, `nil' otherwise. This function ignores differences in
case if `case-fold-search' is non-`nil'.
(char-equal ?x ?X))
=> nil
- - Function: char= CHARACTER1 CHARACTER2
+ - Function: char= character1 character2
This function returns `t' if the arguments represent the same
character, `nil' otherwise. Case is significant.
(char-equal ?x ?X))
=> nil
- - Function: string= STRING1 STRING2
+ - Function: string= string1 string2
This function returns `t' if the characters of the two strings
match exactly; case is significant.
=> nil
- - Function: string-equal STRING1 STRING2
+ - Function: string-equal string1 string2
`string-equal' is another name for `string='.
- - Function: string< STRING1 STRING2
+ - Function: string< string1 string2
This function compares two strings a character at a time. First it
scans both the strings at once to find the first pair of
corresponding characters that do not match. If the lesser

This function returns the property list of SYMBOL.
- - Function: setplist SYMBOL PLIST

This function sets SYMBOL's property list to PLIST. Normally,
PLIST should be a well-formed property list, but this is not
enforced.
For symbols in special obarrays, which are not used for ordinary
purposes, it may make sense to use the property list cell in a
nonstandard fashion; in fact, the abbrev mechanism does so (*note

- - Function: get SYMBOL PROPERTY
+ - Function: get symbol property
This function finds the value of the property named PROPERTY in
SYMBOL's property list. If there is no such property, `nil' is
returned. Thus, there is no distinction between a value of `nil'
See `put' for an example.
- - Function: put SYMBOL PROPERTY VALUE
+ - Function: put symbol property value
This function puts VALUE onto SYMBOL's property list under the
property name PROPERTY, replacing any previous property value.
The `put' function returns VALUE.
These functions are useful for manipulating property lists that are
stored in places other than symbols:
- - Function: getf PLIST PROPERTY &optional DEFAULT
+ - Function: getf plist property &optional default
This returns the value of the PROPERTY property stored in the
property list PLIST. For example,
(getf '(foo 4) 'foo)
=> 4
- - Function: putf PLIST PROPERTY VALUE
+ - Function: putf plist property value
This stores VALUE as the value of the PROPERTY property in the
property list PLIST. It may modify PLIST destructively, or it may
construct a new list structure without altering the old. The
(setq my-plist (putf my-plist 'quux '(a)))
=> (quux (a) bar t foo 5)
- - Function: plists-eq A B
+ - Function: plists-eq a b
This function returns non-`nil' if property lists A and B are
`eq'. This means that the property lists have the same values for
all the same properties, where comparison between values is done
using `eq'.

We control the order of execution of the forms by enclosing them in
"control structures". Control structures are special forms which

special forms since their subforms are not necessarily evaluated or not

- - Special Form: progn FORMS...
+ - Special Form: progn forms...
This special form evaluates all of the FORMS, in textual order,
returning the result of the final form.
Two other control constructs likewise evaluate a series of forms but
return a different value:
- - Special Form: prog1 FORM1 FORMS...
+ - Special Form: prog1 form1 forms...
This special form evaluates FORM1 and all of the FORMS, in textual
order, returning the result of FORM1.
(prog1 (car x) (setq x (cdr x)))
- - Special Form: prog2 FORM1 FORM2 FORMS...
+ - Special Form: prog2 form1 form2 forms...
This special form evaluates FORM1, FORM2, and all of the following
FORMS, in textual order, returning the result of FORM2.
Lisp has two conditional forms: `if', which is much the same as in other
languages, and `cond', which is a generalized case statement.
- - Special Form: if CONDITION THEN-FORM ELSE-FORMS...
+ - Special Form: if condition then-form else-forms...
`if' chooses between the THEN-FORM and the ELSE-FORMS based on the
value of CONDITION. If the evaluated CONDITION is non-`nil',
THEN-FORM is evaluated and the result returned. Otherwise, the
'very-false)
=> very-false
- - Special Form: cond CLAUSE...
+ - Special Form: cond clause...
`cond' chooses among an arbitrary number of alternatives. Each
CLAUSE in the `cond' must be a list. The CAR of this list is the
CONDITION; the remaining elements, if any, the BODY-FORMS. Thus,
`and' and `or' can also be used individually as kinds of multiple
conditional constructs.
- - Function: not CONDITION
+ - Function: not condition
This function tests for the falsehood of CONDITION. It returns
`t' if CONDITION is `nil', and `nil' otherwise. The function
`not' is identical to `null', and we recommend using the name
`null' if you are testing for an empty list.
- - Special Form: and CONDITIONS...

The `throw' need not appear lexically within the `catch' that it

has access to that `catch'. This is why `throw' can be used in

otherwise.

In XEmacs Lisp, definitions serve three purposes. First, they inform

a certain way (as variables). Second, they inform the Lisp system of
these things, supplying a value and documentation. Third, they provide
information to utilities such as `etags' and `make-docfile', which
and override the default values given in the definitions. For this
reason, user options must be defined with `defvar'.
- - Special Form: defvar SYMBOL [VALUE [DOC-STRING]]

This special form defines SYMBOL as a value and initializes it.
The definition informs a person reading your code that SYMBOL is

The usual way to reference a variable is to write the symbol which

you want to do. Occasionally you need to choose at run time which

- - Function: set SYMBOL VALUE
+ - Function: set symbol value
This function sets SYMBOL's value to VALUE, then returns VALUE.
Since `set' is a function, the expression written for SYMBOL is
evaluated to obtain the symbol to set.
One other function for setting a variable is designed to add an
element to a list if it is not already present in the list.
- - Function: add-to-list SYMBOL ELEMENT
+ - Function: add-to-list symbol element
This function sets the variable SYMBOL by consing ELEMENT onto the
old value, if ELEMENT is not already a member of that value. It
returns the resulting list, whether updated or not. The value of

Creating and Deleting Buffer-Local Bindings
-------------------------------------------
- - Command: make-local-variable VARIABLE
+ - Command: make-local-variable variable
This function creates a buffer-local binding in the current buffer
for VARIABLE (a symbol). Other buffers are not affected. The
value returned is VARIABLE.
*Please note:* do not use `make-local-variable' for a hook
variable. Instead, use `make-local-hook'. *Note Hooks::.
- - Command: make-variable-buffer-local VARIABLE
+ - Command: make-variable-buffer-local variable
This function marks VARIABLE (a symbol) automatically
buffer-local, so that any subsequent attempt to set it will make it
local to the current buffer at the time.
The value returned is VARIABLE.
- - Function: local-variable-p VARIABLE &optional BUFFER
+ - Function: local-variable-p variable &optional buffer
This returns `t' if VARIABLE is buffer-local in buffer BUFFER
(which defaults to the current buffer); otherwise, `nil'.
- - Function: buffer-local-variables &optional BUFFER

This function returns a list describing the buffer-local variables
