Why not allocate finalCount on the stack (no point in making work for
yourself). Also, this will leak 4 bytes every time it is called.

Simpler is:

UInt32 finalCount;
Delay((5*60),&finalCount);

That's it!

Cheers,

Steve.

Ok since this has generated alot of mail here's the total code ;)

#include <CoreServices/CoreServices.h>

UInt32 *finalCount;

finalCount = (UInt32*)malloc(sizeof(UInt32));

Delay((5*60),finalCount); //This is a 5 second delay I think since the
doc said a tick is 1/60 of a second...anyway it seems to work for me.

I forgot that part and the program did crash, then I put it in and all
went well.
thanks
Brian

Hmm... Maybe I'm wrong, but couldn't that crash?
Delay returns the final tickcount in the finalCount parameter. In the
code
above, finalCount points to some random memory area, so Delay will write
four bytes into some random place in memory.
I think
UInt32 finalCount;
Delay((5*60),&finalCount);
would be much safer.

Right?
