curses_version, use_extended_names - miscellaneous curses
const char * curses_version(void);
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, prefixed by “ncurses”, e.g.,
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 gtic to compile extended terminal
definitions. However you can disable this feature to ensure compatibility with
other implementations of curses.
curses_version returns a pointer to static memory; you should not free
this in your application.
int use_extended_names(bool enable);
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 conditioned using NCURSES_VERSION.
