how to get the MAC address of the network card

Coding for a Macromedia Director app,
i need to determine via a small C++ Xtra the famous MAC network address,and also all data i can recover from ATA disks and SCSI disks...

Some useful functions to do this are contained in system.h and winio.h under Vc++ on Win

But i need to develope this for MacOs X too..
And as a newbie.. i HAVE to use codewarrior 8.3 and os10.2
(the macromedia SDK is provided of a CodeWarrior template to communicate with Director)

Will be apprecied all about this, the Classes name,the specific functions, the header i have to include...but especially some code sample too from remote urls...i feels lost

Thanks!

The MAC address is available through the System Profiler utility.

:)
would seems obvious i have to organize resulting data into my c++ code
actually i think my c++ Xtra really cannot deal with the system profiler app.
thanks anyway

Really a great ! thanks for tips on man...
i'm a newbie on mac os x .....
sometime a silly thing maybe a big rock

I have written an Xtra that does exactly this. Here is the piece of code from mine to do it. Adapted from code available on Apples developer web site. So, it's only fair I pass it on.

Cheers.
