+ All of these interfaces are provided as macros and functions. The
+ macros are suppressed (and only the functions provided) when
+ <STRONG>NCURSES_OPAQUE</STRONG> is defined. The standard forms such as <STRONG>getyx</STRONG> 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 WINDOW structure.

+ These functions were supported on Version 7, BSD or System V implemen-
+ tations. None of those implementations checked the window parameter.

+ The <STRONG>getattrs</STRONG> function and macro are defined to return a (signed) inte-
+ ger for compatibility with those implementations although an unsigned
+ type would have been more appropriate.
