NAME
       nl_langinfo - query language and locale information

SYNOPSIS
       #include 

       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  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 char-
	      acter 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	 strf-
	      time(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 strf-
	      time(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	 strf-
	      time(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  conven-
	      tion (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 dig-
	      its).

       YESEXPR (LC_MESSAGES)
	      Return a regular expression that can be used with	 the  regex(3)
	      function	to recognize 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 recognize 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 charac-
	      ter.

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

RETURN VALUE
       If  no  locale has been selected for the appropriate category, nl_lang-
       info() 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_langinfo() or setlocale(3).

CONFORMING TO
       SUSv2, POSIX.1-2001.
