I cribbed this from c.l.c++ years ago - don't remember the original
author (but it's not me):
#include

class basic_nullbuf: public std::basic_streambuf {
typename traits::int_type overflow(typename traits::int_type c)

return traits::not_eof(c); // indicate success

basic_onullstream():

std::basic_ostream(&m_sbuf)

init(&m_sbuf);
}
private:
basic_nullbuf m_sbuf;
};
typedef basic_onullstream onullstream;
typedef basic_onullstream wonullstream;
