       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.
       These functions all return TRUE or FALSE, except as noted.
       Both a macro and a function are provided for each name.
       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.
