NL_LANGINFO(3)						   BSD Library Functions Manual 					    NL_LANGINFO(3)

NAME
     nl_langinfo -- language information

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <langinfo.h>

     char *
     nl_langinfo(nl_item item);

     char *
     nl_langinfo_l(nl_item item, locale_t loc);

DESCRIPTION
     The nl_langinfo() function returns a pointer to a string containing information relevant to the particular language or cultural area defined
     in the program or thread's locale, or in the case of nl_langinfo_l(), the locale passed as the second argument.  The manifest constant names
     and values of item are defined in <langinfo.h>.

     Calls to setlocale() with a category corresponding to the category of item, or to the category LC_ALL, may overwrite the buffer pointed to by
     the return value.

RETURN VALUES
     In a locale where langinfo data is not defined, nl_langinfo() returns a pointer to the corresponding string in the POSIX locale.
     nl_langinfo_l() returns the same values as nl_langinfo().	In all locales, nl_langinfo() returns a pointer to an empty string if item con-
     tains an invalid setting.

EXAMPLES
     For example:

	   nl_langinfo(ABDAY_1)

     would return a pointer to the string "Dom" if the identified language was Portuguese, and "Sun" if the identified language was English.

SEE ALSO
