Is it possible to perform <strong>multiple concurrent requests with cpp_netlib</strong> without spawning multiple threads, as it can be done with ASIO asynchronous sockets? I mean a non-blocking manner, something like this:<br> </p> <p>1) Create single io_service object<br> 2) Create and initialize client objects set (all attached to io_service object just created)<br> 3) Call io_service.poll()<br> 4) Check client objects for responses received<br> 5) If some responses has not been received yet, then goto step 3<br> </p> </div> </body> </html> |
