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(3X)

       is_idcok
            returns the value set in idcok(3X)

       is_idlok
            returns the value set in idlok(3X)

       is_immedok
            returns the value set in immedok(3X)

       is_keypad
            returns the value set in keypad(3X)

       is_leaveok
            returns the value set in leaveok(3X)

       is_nodelay
            returns the value set in nodelay(3X)

       is_notimeout
            returns the value set in notimeout(3X)

       is_pad
            returns TRUE if the window is a pad i.e., created by
            newpad(3X)

       is_scrollok
            returns the value set in scrollok(3X)

       is_subwin
            returns TRUE if the window is a subwindow, i.e., created by
            subwin(3X) or derwin(3X)

       is_syncok
            returns the value set in syncok(3X)

       wgetdelay
            returns the delay timeout as set in wtimeout(3X).

       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.
