Table of Contentssetlocale - set the current locale. #include <locale.h>
char *setlocale(int category, const char * locale); 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.
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.
