NAME         top

       curses_version, use_extended_names - miscellaneous curses extensions

SYNOPSIS         top

       #include <curses.h>

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

DESCRIPTION         top

       These functions are extensions to the curses library which do not fit
       easily into other categories.

       Use curses_version to get the version number, including patch level
       of the library, e.g., 5.0.19991023

       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

RETURN VALUE         top

       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.

PORTABILITY         top

       These routines are specific to ncurses.  They were not supported on
       Version 7, BSD or System V implementations.  It is recommended that
       any code depending on them be conditioned using NCURSES_VERSION.
