DESCRIPTION         top

       This implementation provides functions which return properties 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., 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
            windows having no parent.

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

RETURN VALUE         top

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

NOTES         top

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

PORTABILITY         top

       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_VERSION.
