nl_types.h(0p)
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 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 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.
APPLICATION USAGE
None.
RATIONALE
None.
FUTURE DIRECTIONS
