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_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
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.
