I do still recommend clearing the fid after fclose.   This would have caused my fclose

I don't know how to do that -- I use a local copy of the fid, and I see no way to change the value of fid in the calling function.

Oh.  I misunderstood.  I thought that Ben's code was passing you the fid.
I thought that because his code reads:

	  fid = fopen ("test.eps", "wb");
	  drawnow ("eps", sprintf ("%d", fid));

What happens to the fid in the drawnow call?

The fid is passed by value -- it's even passed by it's string value!. The place where I use fclose, in glp-renderer::draw only has the value of fid.
