[Boost-users] Using io_service for synchronous tcp accept + custom tasks

1 Feb 2015

      I've written code of the form:

Code:

io_service svc;
io_service::work work(svc);

thread t1( [&svc]() { svc.run(); } );
thread t2( [&svc]() { svc.run(); } );
thread t3( [&svc]() { svc.run(); } );

endpoint ep(ip::tcp::v4(), port);
acceptor acceptor(svc, ep);

while (true) {
  shared_ptr<socket> sock(new socket(svc));
  acceptor.accept(*sock);

  svc.post( [sock]() {  /* do stuff on sock here */ });
}

Is this way of using io_service for accepting tcp connections and also as a thread pool for serving connected clients valid or could I hit some undefined behavior.
