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.
