NL_LANGINFO(3C) Standard C Library Functions NL_LANGINFO(3C)

NAME

nl_langinfo, nl_langinfo_l - language information

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 null-terminated string
containing information relevant to a particular language or cultural area
defined in the programs locale. The manifest constant names and values of
item are defined by <langinfo.h>. For example:

nl_langinfo(ABDAY_1);

would return a pointer to the string "Dim" if the identified language was
French and a French locale was correctly installed; or "Sun" if the
identified language was English.

The function nl_langinfo_l() behaves identically to nl_langinfo(), except
instead of acting in the current locale, it instead acts in the locale
specified by loc.

RETURN VALUES

If the locale has not been set or is invalid, or if data for a supported
language is either not available, or if item is not defined therein, then
these functions return a pointer to the corresponding string in the C
locale. In all locales, they return a pointer to an empty string if item
contains an invalid setting.
