Detailed Documentation

This stream buffer copies all data written to or read from it to one or multiple output streams.

Construction

TeeStreamBuf()

Creates an unconnected CountingStreamBuf.

Use addStream() to attach output streams.

TeeStreamBuf(std::istream& istr)

Creates the CountingStreamBuf and connects it to the given input stream.

TeeStreamBuf(std::ostream& ostr)

Creates the CountingStreamBuf and connects it to the given output stream.

Methods

void
addStream(std::ostream& ostr)

Adds the given output stream.
