Talk:Windows API

message: There is not a distinct "major version" of the Windows API called Win64.  64-bit editions of Windows implement Win32.  It's the same interface.  Even the "Getting Ready for 64-bit Windows" article cited to support the notion that there is a Win64 is part of the Win32 documentation set (and it never says "Win64").
The reason Win32 is distinct from Win16 is that the API changed in incompatible ways.  For starters, Win16 was the API for an OS that used cooperative multitasking, but Win32 used pre-emptive multitasking, so there were swaths of new functionality (e.g., synchronization objects, virtual memory), fundamental changes to the input and event models, reorganization of the fledgling Windows Registry, and the introduction of long file names. These changes had repercussions that required redesign to portions of the API. Some functions (notably many that dealt with window messages) had to be called with different parameters.  To ease porting from Win16 to Win32, message-crackers and the Win32s overlay were offered to paper over some of the breaking changes.  But most program required some changes to work with the new API.
For 64-bit systems, the API did not need to change in incompatible ways.  The _ABI_ is different (pointer sizes, calling conventions, etc.).  Details of the implementations may be different.  But the _API_ is the same.  The same functions accept the same parameters and return values have the same meaning.
If a Windows program cannot be compiled for both 32- and 64-bit systems, it's due to a non-portable assumption baked into the code about pointer sizes or ranges of representable values—it's not because of an incompatible difference in the Windows API.

replies: text: The article says that "Both 32-bit and 64-bit versions of an application can be compiled from one codebase, although some older API functions have been deprecated, and some of the API functions that were deprecated in Win32 were removed."  The disappearance of deprecated-in-Win32 functions might constitute an API change, although a citation for the claim that some APIs were removed should be provided.

thread_title:  There is no such thing as Win64 

message: An API serves source code portability, it results in being able to compile, then execute programs. The same API can be maintained over multiple instruction sets, e.g. x86, ARM and Power Architecture.
An ABI server binary portability, it results in being able to execute already compiled programs. It is not possible to have the same ABI over different Instruction sets!
This is absolutely not the same. It is much harder to implement and maintain an ABI. In case you want to run already compiled programs, Adobe Photoshop or some Video game, you care about the ABI. ScotXW (talk) 12:02, 27 February 2014 (UTC)

I love how if you look at reference 14, it's a book written in 1998. Yes, clearly modern (2009) programmers will think Windows 1.0 applications look "familiar."  —Preceding unsigned comment added by 173.9.45.237 (talk) 20:33, 29 July 2009 (UTC)

replies: text: I completely rewrote the history section. I still have to add a paragraph on the big win16->win32 move and the introduction of a 64-bit version of the API. Overall though, I've tried to err on the side of too much information, so some of it may need to be trimmed down a bit eventually. Any comments, if anyone is reading this, would be appreciated. --Codemonkey 16:42, 27 August 2005 (UTC)

thread_title:  To do 

message: I removed the citation needed tag from this section - it *is* generally accepted (I have worked on the leading reimplementation of Win32 for years), although if you wanted the legal precedence for this you would have to dig out the Sega case where it was shown that header files cannot be copyrighted.
More specifically, you cannot legally copyright an interface, only an implementation (which the Sega dispute formalised in case law). Therefore because Win32 is an interface (usually but not always paired with the Windows implementation) you can reimplement it legally.
Again I am not sure what you could cite to prove this in the case of Win32 specifically. It's just how copyright law works.

replies: text: according to the article, they are in built in to windows. Just find a compiler that supports them i think. that is normally the case with API's i believe. 12:01, 7 May 2008 (UTC)

text: The API is built right into Windows, so if you have Windows, you already got it. But to have compilers you need, you need the headers and associated tools that describe the API to the compiler. This is available as a part of the Windows SDK (  ). You can use that with the Visual C++ line of compilers and Microsoft Visual Studio IDE (including VC++ Express ). This blog post explains how to use Windows SDK with VC++ Express 2008. The Windows SDK, however, won't allow you to use MinGW or GCC compilers. Use the MinGW Windows runtime/api for an analogous functionality. --soum talk 12:29, 7 May 2008 (UTC)

message: The compiler support section says that "For a long time, the Microsoft Visual Studio family of compilers and tools and Borland's compilers were the only tools that could provide this" (meaning the ability to handle Win32 headers etc.).
In my recollection, this is not true. Before Visual Studio came out, there was Microsoft C/C++, but also Zortech C/C++, Watcom C++ and Turbo C++. Zortech C++ became Symantec C++, was dropped by them, and then bought back by its original author and survives to this day as Digital Mars C++. Watcom was withdrawn from the market before satisfactorily implementing the ARM-level language. Turbo C++ became Borland C++. I owned all three. Watcom and Symantec supplied "memory extenders" which allowed Win32 programs to run on Win16 with Microsoft's redistridutable "win32s" shim DLL. I can't remember why I switched from Borland to Watcom but I think it was because Borland lacked 32-bit support.
I think you'll find the Zortech compiler was the first usable C++ on Win32/Win16, before even Microsoft had one.
Towards the end of this era COM appeared and assumed a certain binary vtable layout. At least Zortech tracked this change. I don't accept that COM is part of Win32, by the way.  — Preceding unsigned comment added by 118.209.147.103 (talk) 07:54, 7 September 2011 (UTC)

message: I've added an infobox. I realize there are 2 things that may seem odd about it, so I thought I would explain:
# I've used a screenshot of ReactOS, as a screenshot of Windows would not be acceptable on Wikimedia Commons. ReactOS, the 3 Windows applications, and the novel Frankenstein can all be licensed under the GPL without issue.
# I saw a place in the software infobox for OS. Currently, I've placed Windows and OS/2 there as these were the only operating systems that were publicly claiming Windows compatibility. ReactOS, Wine, etc. strive for it, but do not have Microsoft's stamp of approval. OS/2 is debatable as it implemented the Windows API up to a certain version. ReactOS could possibly go there, if they explicitly claim to support the Windows API but I think they state something slightly different.

thread_title:  Infobox 

message: The overview section currently lists categories of functions in the API, but I have two concerns about that. 1) Does not seem a good purpose for wikipedia to cover all the technical details of an API. Let the Microsoft docs cover the technical details and let this article cover higher-level concepts -- mostly what's _not_ covered by Microsoft. 2) There's a note saying the list is out-of-date. What would one update to? the latest version? This article is about _all_ versions; not just the latest. Could list the categories for _each_ version, but that's too hard to do and to get right.

thread_title:  communication among different Windows applications 

message: Most of the tech listed as wrappers are not what I'd call a wrapper. IMO a wrapper exposes roughly the same capabilities as the wrapped tech -- just in a different form (interface). Just because one tech uses another tech, does not make it a wrapper. Consuming is not wrapping.
Wrapping requires design intent to replace all consumption need for the underlying tech. For example, MFC and ATL are not intended to replace all consumer need for Windows API.
Taking a step back: What is the point of this section? For example, it says MFC uses Windows API. ok. Everything built for Windows uses Windows API. What is interesting about MFC doing that? Goes without saying. Adds no value.
Suggest: Either remove this section or at least that these other techs are wrappers -- just list them as other Microsoft Windows tech that the reader might want to peruse. Stevebroshar (talk) 11:54, 29 January 2024 (UTC)
