    curs_extend(3x)                  Library calls                 curs_extend(3x)

## 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.
