.SH NAME
\fBcurses_version\fP,
\fBuse_extended_names\fP \- miscellaneous curses extensions
-

.SH SYNOPSIS
\fB#include <curses.h>\fP
-
+.sp
\fBconst char * curses_version(void);\fP
.br
\fBint use_extended_names(bool enable);\fP
.SH DESCRIPTION
These functions are extensions to the curses library
which do not fit easily into other categories.
+.SS curses_version
.PP
-Use
-.I curses_version()
+Use \fBcurses_version\fP
to get the version number, including patch level of the library, e.g.,
.B 5.0.19991023
+.SS use_extended_names
.PP
-The
-.I use_extended_names()
+The \fBuse_extended_names\fP
function controls whether the calling application
is able to use user-defined or nonstandard names
which may be compiled into the terminfo
description, i.e., via the terminfo or termcap interfaces.
-Normally these names are available for use, since the essential descision
-is made by using the \fB-x\fP option of \fItic\fP to compile
+Normally these names are available for use, since the essential decision
+is made by using the \fB\-x\fP option of \fB@TIC@\fP to compile
extended terminal definitions.
However you can disable this feature
-to ensure compatiblity with other implementations of curses

+.SH RETURN VALUE
+.PP
+\fBcurses_version\fP returns a pointer to static memory; you should not free
+this in your application.
+.PP
+\fBuse_extended_names\fP returns the previous state, allowing you to
+save this and restore it.
.SH PORTABILITY
These routines are specific to ncurses. They were not supported on
Version 7, BSD or System V implementations. It is recommended that
\fBcurs_getch\fR(3X),
\fBcurs_mouse\fR(3X),
\fBcurs_print\fR(3X),
+\fBcurs_util\fR(3X),
\fBdefault_colors\fR(3X),
