Does anybody out there know how you can reopen cin, cout and cerr in c++ ? The second 'problem' we came across is the fact that cerr seems to be attached to both stderr and stdout. We are working with Sun's AT&T C++ version 2.0.

Well, those are of type ostream_with_assign . This is an ostream to which you can assign, which is to say that internally it somehow points at the `real' ostream, or at least the real streambuf. It should be possible, then, to create the stream you want, and `assign' it (with operator=() ) to the standard stream that you want to replace. But tell me, please, what do you mean when you say that cerr is attached to both stderr and stdout ? Does an insertion or write to cerr put characters on both stderr and cerr ? I haven't observed anything like this. -- (This man's opinions are his own.) From mole-end Mark Terribile
