Hi,

I'm new at boost, but I don't know how to use the http://beta.boost.org/doc/libs/1_43_0/boost/iostreams/device/null.hpp 

  device.

I must use the boost::iostreams::copy to copy a stream to the /dev/ 

null, but I don't know to declare my out null-output stream.

Can anyone help me to declare the stream?

Okay I've found my error:

I had wrote bio::stream_buffer< bio::basic_null_sink<char> > l_out

and it must be bio::basic_null_sink<char> l_out;
