## NAME

           curses_version,  use_extended_names - miscellaneous curses
           extensions

## SYNOPSIS

           #include <curses.h>

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

## DESCRIPTION

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

### curses_version

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

### use_extended_names

           The use_extended_names()  function  controls  whether  the
           calling  application  is  able to use user-defined or non-
           standard 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 curses.

## RETURN VALUE

           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

           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.
