I am very sorry if this is a FAQ but I have checked the FAQ for this NG
(http://www.plethora.net/%7Eseebs/faqs/clcm.html) and Google ad nauseum but
have not found the information I'm seeking:

{Please note that the above is NOT the FAQ for this newsgroup, but one 
for C. -mod/fwg}

I am using an existing third-party class that uses ostream objects to stream its
output.  I am expected to pass the ostream object (from ostream.h, not
STL::<ostream>) to which this class will write.  But I would like the data written
to this ostream object to be handled by my own code (so I can send it out a
COM IStream interface, if you're interested), not the code from the ostream
implementation in the C/C++ compiler libraries.  What is the best way to do
this?  I can tell all the specifics if you want.

Thank you, Luke Luck (Vic)

You will need to write a custom stream buffer.  This page seems to be a good
start: http://ript.net/~spec/streams/
