Hi
I have a tool that I am running under Mac version of Wine. What I am doing
is installing the tool under wine (i.e wine <path to installer pkg.exe>)
and then running it from wine. It uses an api to capture current screen
(BitBlt api). Under Mac, it is capturing the X windows frame buffer
instead of native Quartz frame buffer. I have source code for this tool. I
am thinking of replacing Windows api for screen capture with Mac's native
apis. I am wondering if someone can point me in right direction.

a) How do I find in code if I am running under regular win32 or wine? If
wine, how do I find host OS (i.e Is it Linux or OS X?)

b) Lets say I know some how what OS the exe is running. I want to call say
LeopardCaptureScreen() on Mac. One way is to include corresponding .h and
link implicitly. But it won't compile under windows. Any pointers on how
to separate this logic in such a way that the mac code can be compiled on
Mac and be loaded under wine.

c) Any pointers on how to capture current screen on Mac OS X. I know it
should be posted under Mac forum, thought of asking here as lot of smart
people are reading this forum.
