Header: Poco/BufferedBidirectionalStreamBuf.h
Description
This is an implementation of a buffered bidirectional streambuf that greatly simplifies the implementation of custom streambufs of various kinds. Derived classes only have to override the methods readFromDevice() or writeToDevice().
In contrast to BasicBufferedStreambuf, this class supports simultaneous read and write access, so in addition to istream and ostream this streambuf can also be used for implementing an iostream.
