Sounds like reinventing the wheel.  The Xt-intrinsics offer a set of functions
that implement the so-called selection mechanism.  Using this mechanism it is
quite easy to transfer large amounts of data from one client to the other;
when the amount meets a limit the intrinsics will handle the chopping in chunks
for you.
So, have a look at XtOwnSelection and friends.
