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(3X)
is_idcok
returns the value set in idcok(3X)
is_idlok
returns the value set in idlok(3X)
is_immedok
returns the value set in immedok(3X)
is_keypad
returns the value set in keypad(3X)
is_leaveok
returns the value set in leaveok(3X)
is_nodelay
returns the value set in nodelay(3X)
is_notimeout
returns the value set in notimeout(3X)
is_pad
returns TRUE if the window is a pad i.e., created by new‐
pad(3X)
is_scrollok
returns the value set in scrollok(3X)
is_subwin
returns TRUE if the window is a subwindow, i.e., created by
subwin(3X) or derwin(3X)
is_syncok
returns the value set in syncok(3X)
wgetdelay
returns the delay timeout as set in wtimeout(3X).
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.
