SETLOCALE(3)						   BSD Library Functions Manual 					      SETLOCALE(3)

NAME

     setlocale -- natural language formatting for C

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <locale.h>

     char *
     setlocale(int category, const char *locale);

DESCRIPTION

     The setlocale() function sets the C library's notion of natural language formatting style for particular sets of routines.  Each such style
     is called a 'locale' and is invoked using an appropriate name passed as a C string.

     The setlocale() function recognizes several categories of routines.  These are the categories and the sets of routines they select:

     LC_ALL	  Set the entire locale generically.

     LC_COLLATE   Set a locale for string collation routines.  This controls alphabetic ordering in strcoll() and strxfrm().

     LC_CTYPE	  Set a locale for the ctype(3) and multibyte(3) functions.  This controls recognition of upper and lower case, alphabetic or non-
		  alphabetic characters, and so on.

     LC_MESSAGES  Set a locale for message catalogs, see catopen(3) function.

     LC_MONETARY  Set a locale for formatting monetary values; this affects the localeconv() function.

     LC_NUMERIC   Set a locale for formatting numbers.	This controls the formatting of decimal points in input and output of floating point num-
		  bers in functions such as printf() and scanf(), as well as values returned by localeconv().

     LC_TIME	  Set a locale for formatting dates and times using the strftime() function.

     Only three locales are defined by default: the empty string "" (which denotes the native environment) and the "C" and "POSIX" locales (which
     denote the C-language environment).  A locale argument of NULL causes setlocale() to return the current locale.  By default, C programs start
     in the "C" locale.  The only function in the library that sets the locale is setlocale(); the locale is never changed as a side effect of
     some other routine.

RETURN VALUES

     Upon successful completion, setlocale() returns the string associated with the specified category for the requested locale.  The setlocale()
     function returns NULL and fails to change the locale if the given combination of category and locale makes no sense.

FILES

     $PATH_LOCALE/locale/category
     /usr/share/locale/locale/category	locale file for the locale locale and the category category.

ERRORS

     No errors are defined.

STANDARDS

     The setlocale() function conforms to ISO/IEC 9899:1999 (``ISO C99'').

     The setlocale() function first appeared in 4.4BSD.

NAME

     locale -- display locale settings

SYNOPSIS

     locale [-a|m]
     locale [-ck] name [...]

DESCRIPTION

     locale displays information about the current locale, or a list of all available locales.

     When locale is run with no arguments, it will display the current source of each locale category.

     When locale is given the name of a category, it acts as if it had been given each keyword in that category.  For each keyword it is given,
     the current value is displayed.

OPTIONS

     -a       Lists all public locales.

     -c name ...
	      Lists the category name before each keyword, unless it is the same category as the previously displayed keyword.

     -k name ...
	      Displays the name of each keyword prior to its value.

     -m       Lists all available public charmaps.  Darwin locales do not support charmaps, so list all CODESETs instead.

OPERANDS

     The following operand is supported:

     name is the name of a keyword or category to display.  A list of all keywords and categories can be shown with the following command:

     locale -ck LC_ALL

ENVIRONMENT

     LANG	  Used as a substitute for any unset LC_* variable.  If LANG is unset, it will act as if set to "C".  If any of LANG or LC_* are
		  set to invalid values, locale acts as if they are all unset.

     LC_ALL	  Will override the setting of all other LC_* variables.

     LC_COLLATE   Sets the locale for the LC_COLLATE category.

     LC_CTYPE	  Sets the locale for the LC_CTYPE category.

     LC_MESSAGES  Sets the locale for the LC_MESSAGES category.

     LC_MONETARY  Sets the locale for the LC_MONETARY category.

     LC_NUMERIC   Sets the locale for the LC_NUMERIC category.

     LC_TIME	  Sets the locale for the LC_TIME category.
