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 C or POSIX, the current locale is set to the portable locale.

If locale is , the locale is set to the default locale which is selected from the environment variable LANG.

On startup of the main program, the portable C locale is selected as default.

The argument category determines which functions are influenced by the new locale:

LC_ALL
for all of the locale.
LC_COLLATE
for the functions strcoll() and strxfrm().
LC_CTYPE
for the character classification and conversion routines.
LC_MONETARY
for localeconv().
LC_NUMERIC
for the decimal character.
LC_TIME
for strftime(). NULL if the request cannot not be honored. This string may be allocated in static storage.

A program may be made portable to all locales by calling setlocale(LC_ALL, ) after program initialization, by using the values returned from a localeconv() call for locale - dependent information and by using strcoll() or strxfrm() to compare strings.  

CONFORMS TO

ANSI C, POSIX.1

Linux supports the portable locales C and POSIX and also the European Latin-1 ISO-8859-1 , and Russian KOI-8 locales.

The printf() family of functions may or may not honor the current locale.
