Talk:DOS Protected Mode Interface

Untitled
This article contains a lot of chatter about other operating systems and things that aren't really relevant to the DPMI interface as it exists. I think some of this belongs in a different article.

 * I did a full rewrite of an overview section now to address this and other concerns. Hope it is now better. Stsp3 (talk) 13:48, 19 December 2021 (UTC)

Version
Are there different API versions out there? Google gave me an unclear result. :-( --RokerHRO (talk) 15:38, 11 September 2011 (UTC)


 * Yes, there are. Officially 0.9 and 1.0, but the story is more complicated than that. However, the article already discusses this. --Matthiaspaul (talk) 20:04, 21 May 2016 (UTC)
 * There is:
 * DPMI 0.9 (a subset of True DPMI)
 * DPMI 1.0 (extends DPMI 0.9 but is incompatible to True DPMI, CWSDPMI which is used by DOS's GNU C Compiler implements this version because True DPMI wasn't known at that time by the developers of CWSDPMI)
 * True DPMI (is used by Windows 3.0, 3.1, Windows 95/98/Me, Borland's C Compiler and Turbo Pascal, thus it is the most important DPMI specification. But it lacks an official public release of the specification. Only some companies like Microsoft and Borland do have that)

Where can the specification for True DPMI, which is not DPMI 1.0, be found?
Windows 3.0, 3.1 and Borlands C Compiler and Turbo Pascal Compiler do make use of the fully True DPMI specification. CWSDPMI on the other side is following the DPMI 1.0 spec, which is something different to True DPMI. The official DPMI 0.9 specification is a subset of True DPMI and DPMI 1.0, but it does not contain everything of True DPMI. So where can the True DPMI specification be found?
