NL_LANGINFO(3)		   Linux Programmers Manual	       NL_LANGINFO(3)



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.  setlocale(3) needs
       to be executed with proper arguments before.

       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_{17} (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_{17} (LC_TIME)
	      Return abbreviated name of the n-th day of the week.

       MON_{112} (LC_TIME)
	      Return name of the n-th month.

       ABMON_{112} (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.
