       curses_version,  use_extended_names - miscellaneous curses
       extensions
       #include <curses.h>
       const char * curses_version(void);
       int use_extended_names(bool enable);
       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 call-
       ing 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 implemen-
       tations of curses.
       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.
       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  con-
       ditioned using NCURSES_VERSION.
