From: stevensmith1010 on 7 May 2008 10:14 Hi, I am trying to port my VC++ application to a x64 compatible platform. Since most of my code makes use of int's ...( I noticed that an int is 32bits long on x64 mode as well)....I want to be able to use 64bit ints in my new code.... I was wondering if there is some option or setting in VC++ tht allows me to treat int's as 64 bit longs or 64 bit integers? Thanks for your valuable suggestions guys.

If you have specific code that would benefit from having 64 bit values, why not use the __int64 type (or have a suitable redefinition for portability). Dave

Nope. In an intuitive world, "long" would be 64 bits in a 64-bit compilation, as it is in gcc, but Microsoft decided we were all too stupid to handle that. In my opinion, that was a huge mistake. -- Tim Roberts, timr(a)probo.com Providenza & Boekelheide, Inc. |
