Yes, this is what I think. This would be a standard way to go. But I
can't remember, for example, a win API that does just that. I will
have to try that.

This is (as we can see it in the md5 unit) a 16 bytes result,
expressed in hex as a 32 char string plus the #0 if a null terminated
string. So memory allocation is always 32+1.
Now I simply want to make that work. I'll need to test that.
Is there anything special to do so that the DLL is working in Windows?
Asside the 'library' program...
