14.10.17.4 Description

This member function reports on whether there is an outstanding (pending) completed request; it does not remove the request. If a completed request is outstanding, the next call to the CORBA::ORB::get_next_response member function is guaranteed to return a request without waiting. If there are no completed requests outstanding, the CORBA::ORB::poll_next_response member function returns without waiting (blocking).
