I am not sure what exactly you mean by full-duplex in this context so I'll
assume that you want to read and write simultaneously rather than in
request-response fashion. In this case you need to break the BSD barrier and
use asynchronous I/O offered by Winsock. Unless you need full Unix
compatibility (and even then) it rarely makes sense to limit yourself to
BSD-style sockets only. They were invented in a different world with
different performance characteristics and application architectures than the
one you develop for.
