## NAME

           is_cleared, is_idlok, is_idcok, is_immedok, is_keypad,
           is_leaveok, is_nodelay, is_timeout, is_scrollok, is_syncok
           - curses window properties

## SYNOPSIS

           #include <curses.h>

           bool is_cleared(const WINDOW *win);
           bool is_idcok(const WINDOW *win);
           bool is_idlok(const WINDOW *win);
           bool is_immedok(const WINDOW *win);
           bool is_keypad(const WINDOW *win);
           bool is_leaveok(const WINDOW *win);
           bool is_nodelay(const WINDOW *win);
           bool is_notimeout(const WINDOW *win);
           bool is_scrollok(const WINDOW *win);
           bool is_syncok(const WINDOW *win);
           WINDOW * wgetparent(const WINDOW *win);
           int wgetscrreg(const WINDOW *win, int *top, int *bottom);

## DESCRIPTION

           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_scrollok
                returns the value set in scrollok

           is_syncok
                returns the value set in syncok

           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

           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  ex-
           tensions be conditioned using NCURSES_VERSION.
