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.

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

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

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.
