NAME
\%curses_version, \%use_extended_names - miscellaneous curses extensions
SYNOPSIS
#include <curses.h>

const char * curses_version(void); int use_extended_names(bool enable);

DESCRIPTION
These functions are extensions to the curses library which do not fit easily into other categories.
curses_version
Use curses_version to get the version number, including patch level of the library, prefixed by \*(``ncurses\*('', e.g.,

ncurses 5.0.19991023

use_extended_names
The use_extended_names 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 -x option of @TIC@ to compile extended terminal definitions. However you can disable this feature to ensure compatibility with other implementations of curses.
RETURN VALUE
curses_version returns a pointer to static memory; you should not free this in your application.

use_extended_names returns the previous state, allowing you to save this and restore it.

EXTENSIONS
These functions are \%ncurses(3X) extensions, and are not found in SVr4 curses , 4.4BSD curses , or any other previous curses implementation.
PORTABILITY
Applications employing \%ncurses extensions should condition their use on the visibility of the \%NCURSES_VERSION preprocessor macro.
