nl_types.h(0P) POSIX Programmer's Manual nl_types.h(0P)
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.
nl_types.h — data types
#include <nl_types.h>
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);
