## DESCRIPTION

           This  implementation  provides functions which return properties set in
           the WINDOW structure, allowing it to be "opaque" if the  symbol  NCURS-
           ES_OPAQUE is defined:

           is_cleared
                returns the value set in clearok

           is_idcok
                returns the value set in idcok

           is_idlok
                returns the value set in idlok

           is_immedok
                returns the value set in immedok

           is_keypad
                returns the value set in keypad

           is_leaveok
                returns the value set in leaveok

           is_nodelay
                returns the value set in nodelay

           is_notimeout
                returns the value set in notimeout

           is_pad
                returns TRUE if the window is a pad i.e., created by newpad

           is_scrollok
                returns the value set in scrollok

           is_subwin
                returns TRUE if the window is a subwindow, i.e., created by subwin
                or derwin

           is_syncok
                returns the value set in syncok

           wgetdelay
                returns the delay timeout as set in wtimeout.

           wgetparent
                returns the parent WINDOW pointer for subwindows, or NULL for win-
                dows having no parent.

           wgetscrreg
                returns the top and bottom rows for the scrolling margin as set in
                wsetscrreg.

## RETURN VALUE

           These functions all return TRUE or FALSE, except as noted.

## NOTES

           Both a macro and a function are provided for each name.

## 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 ncurses extensions be conditioned using  NCURSES_VER-
           SION.
