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

NAME
       curses_version, use_extended_names - miscellaneous curses extensions

SYNOPSIS
       #include <ncursesw/curses.h>

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

DESCRIPTION
       These  ncurses  extensions to the curses library do not fit easily into
       other functional categories.

   curses_version
       curses_version returns a pointer to a string containing  the  library's
       name  and  version  number,  including  its  patch  level,  for example
       “ncurses 6.5.20240720”.

   use_extended_names
       use_extended_names configures whether the library  recognizes  user-de‐
       fined  or  nonstandard  terminfo  capability names that may be compiled
       into  terminal  type  descriptions   via   the   curs_terminfo(3X)   or
       curs_termcap(3X)  interfaces.   Normally  these names are available for
       use, since the essential decision is made through use  of  tic(1)'s  -x
       option  to  include  such  extensions  in  terminal  type descriptions.
       use_extended_names(FALSE) prevents ncurses from recognizing these capa‐
       bilities to ensure compatibility with other implementations of curses.

RETURN VALUE
       curses_version returns a constant string.

       use_extended_names returns the previous state  of  extended  capability
       name recognition, allowing you to save this property and restore it.


ATTRIBUTES

NOTES
       The  pointer returned by curses_version corresponds to statically allo‐
       cated memory; do not attempt to free(3) it.

EXTENSIONS
       These  functions  are  ncurses  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.
