.SH DESCRIPTION
These functions are extensions to the curses library
which do not fit easily into other categories.
.SS curses_version
-.PP
Use \fBcurses_version\fP
to get the version number, including patch level of the library,
prefixed by \*(``ncurses\*('', e.g.,
.B ncurses 5.0.19991023
.RE
.SS use_extended_names
-.PP
The \fBuse_extended_names\fP
function controls whether the calling application
is able to use user-defined or nonstandard names
However you can disable this feature
to ensure compatibility with other implementations of curses.
.SH RETURN VALUE
-.PP
\fBcurses_version\fP returns a pointer to static memory; you should not free
this in your application.
.PP
Version 7, BSD or System V implementations.
It is recommended that
any code depending on them be conditioned using NCURSES_VERSION.
