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
header shall define at least the following types:
- Used by the message catalog functions catopen(),
catgets(), and catclose() to identify a catalog
- Used by nl_langinfo() to identify items of
langinfo data. Values of objects of type nl_item are defined
header shall define at least the following
- 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.
- 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.
The following sections are informative.
char *catgets(nl_catd, int, int, const char *);
nl_catd catopen(const char *, int);
