+.SH DESCRIPTION
+This implementation provides functions which return properties
+set in the WINDOW structure, allowing it to be ``opaque'' if
+the symbol \fBNCURSES_OPAQUE\fR is defined:
+.TP 5
+\fBis_cleared\fR
+returns the value set in \fBclearok\fR
+.TP 5
+\fBis_idcok\fR
+returns the value set in \fBidcok\fR
+.TP 5
+\fBis_idlok\fR
+returns the value set in \fBidlok\fR
+.TP 5
+\fBis_immedok\fR
+returns the value set in \fBimmedok\fR
+.TP 5
+\fBis_keypad\fR
+returns the value set in \fBkeypad\fR
+.TP 5
+\fBis_leaveok\fR
+returns the value set in \fBleaveok\fR
+.TP 5
+\fBis_nodelay\fR
+returns the value set in \fBnodelay\fR
+.TP 5
+\fBis_notimeout\fR
+returns the value set in \fBnotimeout\fR
+.TP 5
+\fBis_scrollok\fR
+returns the value set in \fBscrollok\fR
+.TP 5
+\fBis_syncok\fR
+returns the value set in \fBsyncok\fR
+.TP 5
+\fBwgetparent\fR
+returns the parent WINDOW pointer for subwindows,
+or NULL for windows having no parent.
+.TP 5
+\fBwgetscrreg\fR
+returns the top and bottom rows for the scrolling margin as set in \fBwsetscrreg\fP.
+.SH RETURN VALUE
+These functions all return TRUE or FALSE, except as noted.
+.SH NOTES
+Both a macro and a function are provided for each name.
+.SH 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.
