Hi Milan,



Well aware of IBPP and the fact that Blob's can be manipulated that way.
Was looking to see if there was an example that didn't use IBPP. Our
app currently doesn't use IBPP, although it could - it uses the Zeos
Controls interface package.



The Blob Stream interface I was referring to was part of the
documentation at IBPhoenix.



pbt.

That should be really easy with IBPP:

Probably not. Depends what you find to be easy.

'Stream' as in std::stream?

Perhaps you could write your own fprintf function that does what you
need and remove

#include "stdio.h"

from the file that uses it.
