Editing Windows API (section)

==Other implementations==

[[File:ReactOS Frankenstein Email.png|thumb|[[ReactOS]] is a [[free and open-source software|free and open-source]] operating system that aims to implement the Windows API]]

The [[Wine (software)|Wine]] project provides a Win32 API [[compatibility layer]] for [[Unix-like]] platforms, between [[Linux kernel API]] and programs written for the Windows API. [[ReactOS]] goes a step further and aims to implement the full Windows operating system, working closely with the Wine project to promote code re-use and compatibility. [[DosWin32]] and [[HX DOS Extender]] are other projects which emulate the Windows API to allow executing simple Windows programs from a [[DOS]] command line. [[Odin (code conversion software)|Odin]] is a project to emulate Win32 on [[OS/2]], superseding the original Win-OS/2 emulation which was based on Microsoft code. Other minor implementations include the MEWEL and [[Zinc Application Framework|Zinc]] libraries which were intended to implement a subset of the Win16 API on DOS (see [[List of platform-independent GUI libraries]]).

[[Windows Interface Source Environment]] (WISE) was a licensing program from Microsoft which allowed developers to recompile and run Windows-based applications on [[Unix]] and [[Macintosh]] platforms. WISE SDKs were based on an emulator of the Windows API that could run on those platforms.<ref>[http://hyper.sunjapan.com.cn/~hz/win32/wise.htm WISE] {{webarchive|url=https://web.archive.org/web/20080330032918/http://hyper.sunjapan.com.cn/~hz/win32/wise.htm |date=2008-03-30 }}</ref>

Efforts toward standardization included Sun's [[Public Windows Interface]] (PWI) for Win16 (see also: Sun Windows Application Binary Interface ([[Wabi (software)|Wabi]])), Willows Software's [[Application Programming Interface for Windows]] (APIW) for Win16 and Win32 (see also: [[Willows TWIN]]), and [[ECMA-234]], which attempted to standardize the Windows API bindingly.
