| .SH NAME |
| \fB\%curses_version\fP, |
| \fB\%use_extended_names\fP \- |
| miscellaneous \fIcurses\fR extensions |
| .SH SYNOPSIS |
| .nf |
| \fB#include <curses.h> |
| .PP |
| \fBconst char * curses_version(void); |
| \fBint use_extended_names(bool \fIenable\fP); |
| .fi |
| .SH DESCRIPTION |
| These functions are extensions to the curses library |
| which do not fit easily into other categories. |
| .SS curses_version |
| Use \fBcurses_version\fP |
| to get the version number, including patch level of the library, |
| prefixed by \*(``ncurses\*('', e.g., |
| .RS |
| .sp |
| .B ncurses 5.0.19991023 |
| .RE |
| .SS 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 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 compatibility with other implementations of curses. |
| .SH RETURN VALUE |
| \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 EXTENSIONS |
| These functions are \fB\%ncurses\fP(3X) extensions, |
| and are not found in SVr4 |
| .IR curses , |
| 4.4BSD |
| .IR curses , |
| or any other previous curses implementation. |
| .SH PORTABILITY |
| Applications employing |
| .I \%ncurses |
| extensions should condition their use on the visibility of the |
| .B \%NCURSES_VERSION |
| preprocessor macro. |
