- .SH SYNOPSIS
- .LP
- .nf
- #include <nl_types.h>
- .fi
- .SH DESCRIPTION
- The
- .IR <nl_types.h>
- header shall define at least the following types:
- .IP "\fBnl_catd\fP" 14
- Used by the message catalog functions
- \fIcatopen\fR(),
- \fIcatgets\fR(),
- and
- \fIcatclose\fR()
- to identify a catalog descriptor.
- .IP "\fBnl_item\fP" 14
- Used by
- \fInl_langinfo\fR()
- to identify items of
- .IR langinfo
- data. Values of objects of type
- .BR nl_item
- are defined in
- .IR <langinfo.h> .
- .P
- The
- .IR <nl_types.h>
- header shall define at least the following symbolic constants:
- .IP NL_SETD 14
- Used by
- .IR gencat
- when no $\fIset\fP directive is specified in a message text source
- file. This constant can be passed as the value of
- .IR set_id
- on subsequent calls to
- \fIcatgets\fR()
- (that is, to retrieve messages from the default message set). The
- value of NL_SETD is implementation-defined.
- .IP NL_CAT_LOCALE 14
- Value that must be passed as the
- .IR oflag
- argument to
- \fIcatopen\fR()
- to ensure that message catalog selection depends on the
- .IR LC_MESSAGES
- locale category, rather than directly on the
- .IR LANG
- environment variable.
- .P
- The following shall be declared as functions and may also be defined as
- macros. Function prototypes shall be provided.
