<function>nl_langinfo</function> is used to access individual elements of
the locale categories. Unlike <function>localeconv</function>, which
returns all of the elements, <function>nl_langinfo</function> allows you
to select any specific element.
</para>
<para>
If <parameter>item</parameter> is not valid, &false; will be returned.
</para>
<para>
<parameter>item</parameter> may be an integer value of the element or the
constant name of the element. The following is a list of constant names
for <parameter>item</parameter> that may be used and their description.
Some of these constants may not be defined or hold no value for certain
locales.
