nl_types.h \- data types
|
|
.SH SYNOPSIS
|
|
.LP
|
|
\fB#include <nl_types.h> \fP
|
|
.SH DESCRIPTION
|
|
.LP
|
|
The \fI<nl_types.h>\fP header shall contain definitions of at least
|
|
the following types:
|
|
.TP 7
|
|
\fBnl_catd\fP
|
|
Used by the message catalog functions \fIcatopen\fP(), \fIcatgets\fP(),
|
|
and \fIcatclose\fP() to identify a
|
|
catalog descriptor.
|
|
.TP 7
|
|
\fBnl_item\fP
|
|
Used by \fInl_langinfo\fP() to identify items of \fIlanginfo\fP data.
|
|
Values of
|
|
objects of type \fBnl_item\fP are defined in \fI<langinfo.h>\fP .
|
|
.sp
|
|
.LP
|
|
The \fI<nl_types.h>\fP header shall contain definitions of at least
|
|
the following constants:
|
|
.TP 7
|
|
NL_SETD
|
|
Used by \fIgencat\fP when no $\fIset\fP directive is specified in
|
|
a message text source file; see the Internationalization
|
|
Guide. This constant can be passed as the value of \fIset_id\fP on
|
|
subsequent calls to \fIcatgets\fP() (that is, to retrieve messages
|
|
from the default message set). The value of NL_SETD
|
|
is implementation-defined.
|
|
.TP 7
|
|
NL_CAT_LOCALE
|
|
Value that must be passed as the \fIoflag\fP argument to \fIcatopen\fP()
|
|
to ensure
|
|
that message catalog selection depends on the \fILC_MESSAGES\fP locale
|
|
category, rather than directly on the \fILANG\fP
|
|
environment variable.
