NAMEnl_types.h - data types
SYNOPSIS
#include <nl_types.h>
DESCRIPTION
The <nl_types.h> header shall contain definitions of at least the fol‐
lowing 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. Val‐
ues of objects of type nl_item are defined in <langinfo.h> .
The <nl_types.h> header shall contain definitions of at least the fol‐
lowing constants:
NL_SETD
Used by gencat when no $set directive is specified in a message
text source file; see the Internationalization Guide. This con‐
stant 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.
APPLICATION USAGE
None.
RATIONALE
None.
FUTURE DIRECTIONS
None.
