PROLOG

       This manual page is part of the POSIX Programmer's Manual.  The
       Linux implementation of this interface may differ (consult the
       corresponding Linux manual page for details of Linux behavior),
       or the interface may not be implemented on Linux.

NAME

       nl_types.h — data types

SYNOPSIS

       #include <nl_types.h>

DESCRIPTION

       The <nl_types.h> header shall define at least the following
       types:

       nl_catd       Used by the message catalog functions catopen(),
                     catgets(), and catclose() to identify a catalog
                     descriptor.

       nl_item       Used by nl_langinfo() to identify items of langinfo
                     data. Values of objects of type nl_item are defined
                     in <langinfo.h>.

       The <nl_types.h> header shall define at least the following
       symbolic constants:

       NL_SETD       Used by gencat when no $set directive is specified
                     in a message text source file. This constant can be
                     passed as the value of set_id on subsequent calls
                     to catgets() (that is, to retrieve messages from
                     the default message set). The value of NL_SETD is
                     implementation-defined.

       NL_CAT_LOCALE Value that must be passed as the oflag argument to
                     catopen() to ensure that message catalog selection
                     depends on the LC_MESSAGES locale category, rather
                     than directly on the LANG environment variable.

       The following shall be declared as functions and may also be
       defined as macros. Function prototypes shall be provided.

           int       catclose(nl_catd);
           char     *catgets(nl_catd, int, int, const char *);
           nl_catd   catopen(const char *, int);
