I don't have AutoCAD 2005 to test, so I can will make a guess as to why the
callback function may read more bytes than the amount written. The callback may
be looking for a NULL byte to determine the amount of bytes written, instead of
looking at the using the cb value.

Try making the following change to add the NULL byte that native richedit
controls include, and see if the fixme message still gets printed for the *pcd
value.
