       This implementation provides functions which return  prop-
       erties  set  in  the  WINDOW  structure, allowing it to be
       "opaque" if the symbol NCURSES_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., cre-
            ated 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 windows 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  ex-
       tensions be conditioned using NCURSES_VERSION.
