Linux 2.6 - man page for nl_types.h (linux section 7posix)

<nl_types.h>(P) 		    POSIX Programmer's Manual			  <nl_types.h>(P)

NAME
       nl_types.h - data types

SYNOPSIS
       #include <nl_types.h>

DESCRIPTION
       The <nl_types.h> header shall contain definitions of at least the following types:

       nl_catd
	      Used by the message catalog functions catopen(), catgets(), and catclose() to iden-
	      tify 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 contain definitions of at least the following constants:

       NL_SETD
	      Used  by	gencat when no $set directive is specified in a message text source file;
	      see the Internationalization Guide. 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);

       The following sections are informative.
