Re: [Boost-users] wrapping stdlib fstream with boost filtering streams

Two open questions that come to mind:

1) does the compressor flush the zlib compression buffer when I flush/ pop it?

As I understand it, pop() and reset() both flush and close the current device and then destroy it.

2) is fstream a bidirectional stream (my guess due to separate seekg/ seekp methods) or a seekable stream (one read/write head)? Because I currently require the former.

btw: the above code runs without exceptions, but when I read back variables I have just written they are garbled.
