The macros BOOST_IOSTREAMS_DEFAULT_DEVICE_BUFFER_SIZE, BOOST_IOSTREAMS_DEFAULT_FILTER_BUFFER_SIZE and BOOST_IOSTREAMS_DEFAULT_PBACK_BUFFER_SIZE can be used to configure the default sizes of buffers allocated by the Iostreams library when a Filter or Device is attached to a stream_buffer or stream, or when it is added to a chain.
The default values are subject to change in future versions of the Iostreams library.
