How to drop a request in the Client/Server

[leiBravo]

in the request response example iceoryx_examples/request_response/client_cxx_waitset.cpp
if the time is up, how can i drop the request

        // We block and wait for samples to arrive, when the time is up we send the request again
        //! [wait and check if the client triggered]
        auto notificationVector = waitset.timedWait(iox::units::Duration::fromSeconds(5));
        if (notificationVector.empty()) {
            std::cout << "time out occur" << std::endl;
            // TODO: timeout occur, so how can i drop current request
            continue;
        }

You can't. But it is possible to send another request and if you are unsure to which request the received response belongs you can take a look at line 113 (in client_cxx_waitset.cpp)..., here we perform a sequence id check to match the request with the response:

                while (client.take().and_then([&](const auto& response) {
                    auto receivedSequenceId = response.getResponseHeader().getSequenceId();
                    if (receivedSequenceId == ctx.expectedResponseSequenceId)
