nl_types.h - data types
Návod, kniha: POSIX Programmer's Manual
#include <nl_types.h>
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);
