Microsoft Windows Win32 API Reference Standard codified in ECMA-234 vol 3 (Dec 1995)

ECMA-234 vol 3 , 190pp of Win32 API. (valuable Ratified Standard of OS calls) This large book of Microsoft Windows API standard calls are accessible in every version of Windows from MS Windows 3.1 to MS Windows 8.1 desktop, yet only game coders and utility authors seem to work at that level of interface in C. Nevertheless this is the full public defined Windows Win32 API prior to Win32c. Charles Petzold's "Programming Windows" Win32 books are useful exept his 2012 and later books that omit this and use only C# calls. Manuals such as this one are rare to find. This is a useful fundamental reference, applicable even in 2013, to craft code that runs on any MS Windows device in history. The Win32 was frozen in Dec 1995, and in modern OSes it is of course an abstraction layer with some direct low level hooks. Using just this manual and a C compiler and a free download of Windows SDK library and headers, a programmer could design GUI apps that run on anything.
