NAME

13       nl_types.h — data types
14

SYNOPSIS

16       #include <nl_types.h>
17

DESCRIPTION

19       The <nl_types.h> header shall define at least the following types:
20
21       nl_catd       Used by the message  catalog  functions  catopen(),  cat‐
22                     gets(), and catclose() to identify a catalog descriptor.
23
24       nl_item       Used by nl_langinfo() to identify items of langinfo data.
25                     Values of objects of type nl_item are defined  in  <lang‐
26                     info.h>.
27
28       The  <nl_types.h>  header  shall define at least the following symbolic
29       constants:
30
31       NL_SETD       Used by gencat when no $set directive is specified  in  a
32                     message  text source file. This constant can be passed as
33                     the value of set_id  on  subsequent  calls  to  catgets()
34                     (that  is,  to retrieve messages from the default message
35                     set). The value of NL_SETD is implementation-defined.
36
37       NL_CAT_LOCALE Value that must  be  passed  as  the  oflag  argument  to
38                     catopen()   to  ensure  that  message  catalog  selection
39                     depends on the LC_MESSAGES locale category,  rather  than
40                     directly on the LANG environment variable.
41
42       The following shall be declared as functions and may also be defined as
43       macros. Function prototypes shall be provided.
44
45           int       catclose(nl_catd);
46           char     *catgets(nl_catd, int, int, const char *);
47           nl_catd   catopen(const char *, int);
