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 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.
