-.SH NOTES
-All of these interfaces are implemented as macros and functions.
-The macros are suppressed
-(and only the functions provided)
-in an \*(``opaque\*(''
-.I \%ncurses
-build,
-which defines the preprocessor symbol
-.BR \%NCURSES_OPAQUE .
-See section \*(``ALTERNATE CONFIGURATIONS\*('' in \fB\%ncurses\fP(3X).
-.PP
-The standard forms such as \fB\%getyx\fP
-.I must
-be implemented as macros,
-and
-(in this implementation)
-are defined in terms of the functions described here,
-to avoid reliance on internal details of the \fI\%WINDOW\fP structure.
