NL_LANGINFO(3)			    Linux Programmer's Manual			   NL_LANGINFO(3)

NAME
       nl_langinfo - query language and locale information

SYNOPSIS
       #include <langinfo.h>

       char *nl_langinfo(nl_item *item);

DESCRIPTION
       The nl_langinfo function provides access to locale information in a more flexible way than
       localeconv(3) does. Individual and additional elements of the  locale  categories  can  be
       queried.

       Examples for the locale elements that can be specified in item using the constants defined
       in <langinfo.h> are:

       CODESET (LC_CTYPE)
	      Return a string with the name of	the  character	encoding  used	in  the  selected
	      locale,  such  as  "UTF-8",  "ISO-8859-1", or "ANSI_X3.4-1968" (better known as US-
	      ASCII). This is the same string that you get with "locale charmap". For a  list  of
	      character encoding names, try "locale -m", cf. locale(1).

       D_T_FMT (LC_TIME)
	      Return  a  string  that can be used as a format string for strftime(3) to represent
	      time and date in a locale-specific way.

       D_FMT (LC_TIME)
	      Return a string that can be used as a format string for strftime(3) to represent	a
	      date in a locale-specific way.

       T_FMT (LC_TIME)
	      Return  a string that can be used as a format string for strftime(3) to represent a
	      time in a locale-specific way.

       DAY_{1-7} (LC_TIME)
	      Return name of the n-th day of the week. [Warning: this follows the  US  convention
	      DAY_1  =	Sunday,  not  the  international convention (ISO 8601) that Monday is the
	      first day of the week.]

       ABDAY_{1-7} (LC_TIME)
	      Return abbreviated name of the n-th day of the week.

       MON_{1-12} (LC_TIME)
	      Return name of the n-th month.

       ABMON_{1-12} (LC_TIME)
	      Return abbreviated name of the n-th month.

       RADIXCHAR (LC_NUMERIC)
	      Return radix character (decimal dot, decimal comma, etc.).

       THOUSEP (LC_NUMERIC)
	      Return separator character for thousands (groups of three digits).

       YESEXPR (LC_MESSAGES)
	      Return a regular expression that can be used with the regex(3) function  to  recog-
	      nize a positive response to a yes/no question.

       NOEXPR (LC_MESSAGES)
	      Return  a  regular expression that can be used with the regex(3) function to recog-
	      nize a negative response to a yes/no question.

       CRNCYSTR (LC_MONETARY)
	      Return the currency symbol, preceded by "-" if the symbol should appear before  the
	      value, "+" if the symbol should appear after the value, or "." if the symbol should
	      replace the radix character.

       The above list covers just some examples of items  that	can  be  requested.  For  a  more
       detailed list, please consult The GNU C Library Reference Manual.

RETURN VALUE
       If no locale has been selected for the appropriate category, nl_langinfo returns a pointer
       to the corresponding string in the "C" locale.

       If item is not valid, a pointer to an empty string is returned.

       This pointer may point to static data that may be overwritten on the next call to nl_lang-
       info or setlocale.
