FUNCTION
<<strerror_r>>---convert error number to string and copy to buffer
INDEX
strerror_r
ANSI_SYNOPSIS
#include <string.h>
#ifdef _GNU_SOURCE
char *strerror_r(int <[errnum]>, char *<[buffer]>, size_t <[n]>);
#else
int strerror_r(int <[errnum]>, char *<[buffer]>, size_t <[n]>);

TRAD_SYNOPSIS
#include <string.h>
char *strerror_r(<[errnum]>, <[buffer]>, <[n]>)
int <[errnum]>;
char *<[buffer]>;
size_t <[n]>;
DESCRIPTION
<<strerror_r>> converts the error number <[errnum]> into a
string and copies the result into the supplied <[buffer]> for
a length up to <[n]>, including the NUL terminator. The value of
<[errnum]> is usually a copy of <<errno>>. If <<errnum>> is not a known
error number, the result is the empty string.
See <<strerror>> for how strings are mapped to <<errnum>>.
RETURNS
There are two variants: the GNU version always returns a NUL-terminated
string, which is <[buffer]> if all went well, but which is another
pointer if <[n]> was too small (leaving <[buffer]> untouched). If the
return is not <[buffer]>, your application must not modify that string.
The POSIX version returns 0 on success, <[EINVAL]> if <<errnum>> was not
recognized, and <[ERANGE]> if <[n]> was too small. The variant chosen
depends on macros that you define before inclusion of <<string.h>>.
PORTABILITY
<<strerror_r>> with a <[char *]> result is a GNU extension.
<<strerror_r>> with an <[int]> result is required by POSIX 2001.
This function is compliant only if <<_user_strerror>> is not provided,
or if it is thread-safe and uses separate storage according to whether
the second argument of that function is non-zero. For more details
on <<_user_strerror>>, see the <<strerror>> documentation.
POSIX states that the contents of <[buf]> are unspecified on error,
although this implementation guarantees a NUL-terminated string for
all except <[n]> of 0.
POSIX recommends that unknown <[errnum]> result in a message including
that value, however it is not a requirement and this implementation
provides only an empty string (unless you provide <<_user_strerror>>).
POSIX also recommends that unknown <[errnum]> fail with EINVAL even
when providing such a message, however it is not a requirement and
this implementation will return success if <<_user_strerror>> provided
a non-empty alternate string without assigning into its third argument.
<<strerror_r>> requires no supporting OS subroutines.

DESCRIPTION
The <<wcpncpy>> function copies not more than n wide-character codes
(wide-character codes that follow a null wide-character code are not
copied) from the array pointed to by <[s2]> to the array pointed to
by <[s1]>. If copying takes place between objects that overlap, the
behaviour is undefined.
If the array pointed to by <[s2]> is a wide-character string that is
shorter than <[n]> wide-character codes, null wide-character codes are
appended to the copy in the array pointed to by <[s1]>, until <[n]>
wide-character codes in all are written.
RETURNS
The <<wcpncpy>> function returns <[s1]>; no return value is reserved to
indicate an error.
PORTABILITY
<<wcpncpy>> is ISO/IEC 9899/AMD1:1995 (ISO C).
No supporting OS subroutines are required.

FUNCTION
<<wcsstr>>---find a wide-character substring
ANSI_SYNOPSIS
#include <wchar.h>
wchar_t *wcsstr(const wchar_t *__restrict <[big]>,
const wchar_t *__restrict <[little]>);
TRAD_SYNOPSIS
wchar_t *wcsstr(<[big]>, <[little]>
const wchar_t *__restrict <[big]>;
const wchar_t *__restrict <[little]>;
DESCRIPTION
The <<wcsstr>> function locates the first occurrence in the
wide-character string pointed to by <[big]> of the sequence of
wide characters (excluding the terminating null wide character) in the
wide-character string pointed to by <[little]>.
RETURNS
On successful completion, <<wcsstr>> returns a pointer to the located
wide-character string, or a null pointer if the wide-character string
is not found.
If <[little]> points to a wide-character string with zero length,
the function returns <[big]>.
PORTABILITY
<<wcsstr>> is ISO/IEC 9899/AMD1:1995 (ISO C).

FUNCTION
<<wcstok>>---get next token from a string
INDEX
wcstok
ANSI_SYNOPSIS
#include <wchar.h>
wchar_t *wcstok(wchar_t *__restrict <[source]>,
const wchar_t *__restrict <[delimiters]>,
wchar_t **__restrict <[lasts]>);
TRAD_SYNOPSIS
#include <wchar.h>
wchar_t *wcstok(<[source]>, <[delimiters]>, <[lasts]>);
wchar_t *__restrict <[source]>;
wchar_t *__restrict <[delimiters]>;
wchar_t **__restrict <[lasts]>;
DESCRIPTION
The <<wcstok>> function is the wide-character equivalent of the
<<strtok_r>> function (which in turn is the same as the <<strtok>>
function with an added argument to make it thread-safe).
The <<wcstok>> function is used to isolate (one at a time)
sequential tokens in a null-terminated wide-character string,
<<*<[source]>>>. A token is defined as a substring not containing
any wide-characters from <<*<[delimiters]>>>.
The first time that <<wcstok>> is called, <<*<[source]>>> should
be specified with the wide-character string to be searched, and
<<*<[lasts]>>>--but not <<lasts>>, which must be non-NULL--may be
random; subsequent calls, wishing to obtain further tokens from
the same string, should pass a null pointer for <<*<[source]>>>
instead but must supply <<*<[lasts]>>> unchanged from the last
call. The separator wide-character string, <<*<[delimiters]>>>,
must be supplied each time and may change between calls.
A pointer to placeholder <<*<[lasts]>>> must be supplied by
the caller, and is set each time as needed to save the state
by <<wcstok>>. Every call to <<wcstok>> with <<*<[source]>>>
== <<NULL>> must pass the value of <<*<[lasts]>>> as last set
by <<wcstok>>.
The <<wcstok>> function returns a pointer to the beginning of each
subsequent token in the string, after replacing the separator
wide-character itself with a null wide-character. When no more tokens
remain, a null pointer is returned.
RETURNS
<<wcstok>> returns a pointer to the first wide character of a token, or
<<NULL>> if there is no token.
NOTES
<<wcstok>> is thread-safe (unlike <<strtok>>, but like <<strtok_r>>).
<<wcstok>> writes into the string being searched.
PORTABILITY
<<wcstok>> is C99 and POSIX.1-2001.
<<wcstok>> requires no supporting OS subroutines.

/*
* This is an implementation of wcwidth() (defined in
* IEEE Std 1002.1-2001) for Unicode.
*
* http://www.opengroup.org/onlinepubs/007904975/functions/wcwidth.html
*
* In fixed-width output devices, Latin characters all occupy a single
* "cell" position of equal width, whereas ideographic CJK characters
* occupy two such cells. Interoperability between terminal-line
* applications and (teletype-style) character terminals using the
* UTF-8 encoding requires agreement on which character should advance
* the cursor by how many cell positions. No established formal
* standards exist at present on which Unicode character shall occupy
* how many cell positions on character terminals. These routines are
* a first attempt of defining such behavior based on simple rules
* applied to data provided by the Unicode Consortium.
*
* For some graphical characters, the Unicode standard explicitly
* defines a character-cell width via the definition of the East Asian
* FullWidth (F), Wide (W), Half-width (H), and Narrow (Na) classes.
* In all these cases, there is no ambiguity about which width a
* terminal shall use. For characters in the East Asian Ambiguous (A)
* class, the width choice depends purely on a preference of backward
* compatibility with either historic CJK or Western practice.
* Choosing single-width for these characters is easy to justify as
* the appropriate long-term solution, as the CJK practice of
* displaying these characters as double-width comes from historic
* implementation simplicity (8-bit encoded characters were displayed
* single-width and 16-bit ones double-width, even for Greek,
* Cyrillic, etc.) and not any typographic considerations.
*
* Much less clear is the choice of width for the Not East Asian
* (Neutral) class. Existing practice does not dictate a width for any
* of these characters. It would nevertheless make sense
* typographically to allocate two character cells to characters such
* as for instance EM SPACE or VOLUME INTEGRAL, which cannot be
* represented adequately with a single-width glyph. The following
* routines at present merely assign a single-cell width to all
* neutral characters, in the interest of simplicity. This is not
* entirely satisfactory and should be reconsidered before
* establishing a formal standard in this area. At the moment, the
* decision which Not East Asian (Neutral) characters should be
* represented by double-width glyphs cannot yet be answered by
* applying a simple rule from the Unicode database content. Setting
* up a proper standard for the behavior of UTF-8 character terminals
* will require a careful analysis not only of each Unicode character,
* but also of each presentation form, something the author of these
* routines has avoided to do so far.

wchar_t *wmemchr(const wchar_t *<[s]>, wchar_t <[c]>, size_t <[n]>);
TRAD_SYNOPSIS
wchar_t *wmemchr(<[s]>, <[c]>, <[n]>
const wchar_t *<[s]>;
wchar_t <[c]>;
size_t <[n]>;
DESCRIPTION
The <<wmemchr>> function locates the first occurrence of <[c]> in the
initial <[n]> wide characters of the object pointed to be <[s]>. This
function is not affected by locale and all wchar_t values are treated
identically. The null wide character and wchar_t values not
corresponding to valid characters are not treated specially.
If <[n]> is zero, <[s]> must be a valid pointer and the function
behaves as if no valid occurrence of <[c]> is found.
RETURNS
The <<wmemchr>> function returns a pointer to the located
wide character, or a null pointer if the wide character does not occur
in the object.
PORTABILITY
<<wmemchr>> is ISO/IEC 9899/AMD1:1995 (ISO C).
No supporting OS subroutines are required.

corresponding to valid characters are not treated specially.
If <[n]> is zero, <[s]> must be a valid pointer and the function
copies zero wide characters.
RETURNS
The <<wmemset>> function returns the value of <[s]>.
PORTABILITY
<<wmemset>> is ISO/IEC 9899/AMD1:1995 (ISO C).
No supporting OS subroutines are required.
