SETLOCALE(3) Linux Programmer's Manual SETLOCALE(3)
NAME
setlocale - set the current locale
SYNOPSIS
#include <locale.h>
char *setlocale(int category, const char *locale);
DESCRIPTION
The setlocale() function is used to set or query the program's current
locale.
If locale is not NULL, the program's current locale is modified accord‐
ing to the arguments. The argument category determines which parts of
the program's current locale should be modified. lB lB lB l. Cate‐
gory Governs LC_ALL All of the locale LC_ADDRESS T{ Formatting
of addresses and
geography-related items (*) T} LC_COLLATE String collation
LC_CTYPE Character classification LC_IDENTIFICATION Metadata de‐
scribing the locale (*) LC_MEASUREMENT T{ Settings related to measure‐
ments
(metric versus US customary) (*) T} LC_MESSAGES Localizable natural-
language messages LC_MONETARY Formatting of monetary values
LC_NAME Formatting of salutations for persons (*) LC_NUMERIC For‐
matting of nonmonetary numeric values LC_PAPER Settings related to the
standard paper size (*) LC_TELEPHONE Formats to be used with tele‐
phone services (*) LC_TIME Formatting of date and time values
The categories marked with an asterisk in the above table are GNU ex‐
tensions. For further information on these locale categories, see lo‐
cale(7).
The argument locale is a pointer to a character string containing the
required setting of category. Such a string is either a well-known
constant like "C" or "da_DK" (see below), or an opaque string that was
returned by another call of setlocale().
If locale is an empty string, "", each part of the locale that should
be modified is set according to the environment variables. The details
are implementation-dependent. For glibc, first (regardless of cate‐
gory), the environment variable LC_ALL is inspected, next the environ‐
ment variable with the same name as the category (see the table above),
and finally the environment variable LANG. The first existing environ‐
ment variable is used. If its value is not a valid locale specifica‐
tion, the locale is unchanged, and setlocale() returns NULL.
The locale "C" or "POSIX" is a portable locale; it exists on all con‐
forming systems.
A locale name is typically of the form language[_territory][.code‐
set][@modifier], where language is an ISO 639 language code, territory
is an ISO 3166 country code, and codeset is a character set or encoding
identifier like ISO-8859-1 or UTF-8. For a list of all supported lo‐
cales, try "locale -a" (see locale(1)).
If locale is NULL, the current locale is only queried, not modified.
On startup of the main program, the portable "C" locale is selected as
default. A program may be made portable to all locales by calling:
setlocale(LC_ALL, "");
after program initialization, by using the values returned from a lo‐
caleconv(3) call for locale-dependent information, by using the multi‐
byte and wide character functions for text processing if MB_CUR_MAX >
1, and by using strcoll(3), wcscoll(3) or strxfrm(3), wcsxfrm(3) to
compare strings.
RETURN VALUE
A successful call to setlocale() returns an opaque string that corre‐
sponds to the locale set. This string may be allocated in static stor‐
age. The string returned is such that a subsequent call with that
string and its associated category will restore that part of the
process's locale. The return value is NULL if the request cannot be
honored.

CONFORMING TO
POSIX.1-2001, POSIX.1-2008, C89, C99.
The C standards specify only the categories LC_ALL, LC_COLLATE,
LC_CTYPE, LC_MONETARY, LC_NUMERIC, and LC_TIME. POSIX.1 adds LC_MES‐
SAGES. The remaining categories are GNU extensions.
