Hi there,<br>
<br>
In an attempt to create a Windows 64bit version, Blender needs an<br>
official way to deal with the fact that:<br>
<br>
long is 32bit on Win64 (LP64)<br>
long is 64bit on Linux64/Mac64 (LLP64)<br>
<br>
<br>
So the whole long-pointer casting is kind of going wrong on Win64 and<br>
therefore crashing Blender.<br>
<br>
As a proposal I suggest not to use "long" but to introduce the C99/C9X<br>
standard type "uintptr_t" which is already used in many header of the<br>
libs which Blender uses (ffmpeg, python, X264, SDL). This type would<br>
allow instant pointer fiddling and cross plattform compatibility between<br>
LLP64 and LP64 plattforms.<br>
<br>
I would also search-replace the existing "long"s in Blender.<br>
<br>
The goal for this is post-2.47 so we can test it on several plattforms<br>
and harden it a bit (e.g. some older compilers don't define that<br>
uintptr_t type).<br>
<br>
Any comments / suggestions?<br>
<br>
Greetings<br>
Daniel / Genscher<br>
