The function you need is in a vm plugin, so code for it will exist in two
a) the Slang code that is part of the VMMaker package. In particular, look for
the FileCopyPlugin class. Note that it seems incomplete, but see also...
b) the platforms tree as downloaded from the SVN server, in particular the

Now, as we've mentioned it won't be there for windows yet, so you'd have to
read the other platform implementations to get the idea. All you need to do is
implement sqInt sqCopyFilesizetosize(char *srcName, sqInt srcNameSize, char
*dstName, sqInt dstNameSize) and build the plugin.

This _ought_ to be doable by reading the relevant swiki pages so please try it
that way and please make notes about what isn't explained etc so we can improve
the doc. Only by outside reviewers providing feedback can it get better.

Why the fear? VMMaker is incredibly simple to use; load it from SqueakMap,

would be to pre-press the button for you ;-)

[*] there are a few plugins whose code is not in the VMMaker package. Nothing
to worry about right now.
