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 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_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 extensions be conditioned using NCURSES_VERSION.
