Cheers Angus,

Looking good.  One query...

So a function that 'gets' something would need to look like..

GMPI_RESULT GetFlags(int *flags){ *flags = 123456;};

..and be called like...

int flags;
GetFlags ( &flags );

i.e. it can't just return something, you've got to pass in a pointer-to-something.

That will work, but is a little awkward.  What do people think?

Best Regards,
jeff
