Hi

I've noticed that __dpmi_allocate_dos_memory has superseded (and much
simplified) calling this DPMI function, over the
_go32_dpmi_allocate_dos_memory equivalent.

But the routine gives you back just a selector and a segment.

So if I have a structure MyStruct, I want to call like this:

movedata( _my_ds(), (int )&MyStruct, DosSelector, 0, sizeof( MyStruct));

Is this right?

My question is about the 0 ... I have just assumed this is the offset to
use, because there is no offset returned. Likewise when I pass the segment
returned from the allocate to __dpmi_int with an es:ebx combination: I
assume again that the allocation aligns it on a segment boundary?

Or am I doing something seriously wrong? (BTW, the code doesn't work... in
case you haven't guessed :)

Thanks,
Brett
