NAME
nl_langinfo() — language information
SYNOPSIS
#include <langinfo.h>
char *nl_langinfo(nl_item item);
DESCRIPTION
nl_langinfo()
returns a pointer to a null-terminated string
containing information relevant to a particular language
or cultural area defined in the program's locale (see
setlocale(3C)).
The manifest constant names and values of
item
are defined in
<langinfo.h>.
For example:
returns a pointer to the string ``Dom''
if the language identified by the current locale is pt_PT.iso88591,
and ``Su'' if the identified language is fi_FI.iso88591.
If an invalid
item
is specified, a pointer to an empty string is returned.
An empty string can also be returned for a valid
item
if that item
is not applicable to the language or customs of the current locale.
For example, a thousands separator is not used
when writing numbers
according to the customs associated with the Arabic language.
EXTERNAL INFLUENCES

The string returned for a particular
item
is determined by the locale category specified for that item in
langinfo(5).
