[Boost-users] unexpected behaviour of filtering_ostream

I have the following code: int main(int argc, char *argv[]) {     io::filtering_ostream out;     out.push(std::cout);     out << "this is a test" << endl;     out << std::cin.rdbuf(); } when I run it the string "this is a test" gets sent to cout, but input type into cin does not get echoed to cout. Can anyone clue my in as to why not?     -EdK   Ed Keith e_d_k@yahoo.com Blog: edkeith.blogspot.com
