FAR and 64 bit?

NTDEV
1

Hello,

I noticed plenty of:

//
// Make sure FAR is defined...
//
#ifndef FAR
#ifdef _WIN32
#define FAR
#else
#define FAR _far
#endif
#endif

In various Windows headers, including in the latest DDKs. Am I right to
assume that _WIN32 will not be defined for 64 bit environments and all the
old 32 bit code using FAR for compatibility with 16 bit assuming that FAR
will be replace by empty string is now having FAR replaced again by _far?
Would it have any consequence?

Best regards,

David Burg

The LDK has FAR defined as nothing everywhere I looked - wdm.h & ntddk.h.
It is not conditional on 32 or 64 bit environments.

Interesting … that code snippet looks a bit familiar to me … where exactly did you find this ?

No. _WIN32 is always defined, even on 64-bit Windows. Too much code
would break if MSFT did anything else.

Hello,

In build 3790 of DDK, you can make a search in file. Some sample of
occurances:

C:\WINDDK\3790\INC\ddk\w2k\ntddscsi.h(37):#define FAR
C:\WINDDK\3790\INC\ddk\w2k\ntddser.h(38):#define FAR
C:\WINDDK\3790\INC\ddk\w2k\ntddstor.h(37):#define FAR
C:\WINDDK\3790\INC\ddk\wnet\diskguid.h(33):#define FAR
C:\WINDDK\3790\INC\ddk\wnet\ntddscsi.h(37):#define FAR
C:\WINDDK\3790\INC\ddk\wnet\ntddser.h(38):#define FAR
C:\WINDDK\3790\INC\ddk\wnet\ntddstor.h(37):#define FAR
Etc...

Thanks for the information. :slight_smile: Good to know there is no worry to have about
'far' pointers.

However it does not sound very good to keep dummy FAR definition for 16 bits
code compatibility, plus _WIN32 definition, we actually it is code for a 64
bit platform that is been created. Maybe some maintenance work to clean up
old stuff could be done there.

It is very difficult for Microsoft to change ANY standard header file
definitions. In general the best they can do is to pile on new stuff over
the old cruft. The 16bit crap is here to stay until the last dos app is
dead, which ought to be somewhere around 2104.

Mark, will human beings ever use computer at that time? I'm sure something
better would have been invented. Computer is just evil and introduces more
problems than it has solved ever IMHO-:).

But why would a DOS program author use Windows .NET DDK? :-?

The last *real* invention ( not counting *evolution* and *re-invention* ) I know about is the semiconducter somewhere around 1947. Ever heard about the “middle ages” ? I am not so optimistic as you are :slight_smile:

MessageYep, I've been wondering for digitized bread and butter for quite
some time :). Let me know which model should I buy !

Is it those colorful Mac that produces bread and Jam(s) like with grapes,
berries, orange, peach ... :slight_smile: I bet they would be full of particles with
cristals (1) and vaccume(0). Teeth will have real challenge :slight_smile:

And it will surely straighten my thinking as Garry L explained ( dinna ....

They very likely won't.

But the headers in the DDK are copied or generated from the headers we
use in the product, which occasionally need to be used to build some
16-bit component for our own legacy support, or which also get put in
the SDK which is (sadly) concerned about such matters.

In the end this approach is still better than some of the old ways we've
generated the DDK, even if it does have a little more seemingly
pointless cruft in it.
