[Cppcms-users] Communication between synchronous and asynchronous applications

[CN <cn...@fa...>]

Hello!

Imagine I have both synchronous and asynchronous applications mounted:

int main(int argc,char ** argv)
{
    try {
        cppcms::service srv(argc,argv);

        srv.applications_pool().mount(cppcms::applications_factory<my_hello_world>());

        booster::intrusive_ptr<chat> c=new chat(srv);
        service.applications_pool().mount(c);

        srv.run();
    }
    catch(std::exception const &e) {
        std::cerr<<e.what()<<std::endl;
    }
}

Assume that
std::vector<cppcms::json::value> messages_;
in
http://cppcms.com/wikipp/en/page/cppcms_1x_chat_json_rpc
is public.

If I understand the framework correctly, asynchronous applications run
in main thread. Therefore, asynchronous applications are appropriate
candidates to keep cross-application data, messages_ in our example,
that is to be shared by synchronous applications.

I would like to know how to access messages_ kept in chat application
from my_hello_world.  I have read both

http://cppcms.com/wikipp/en/page/cppcms_1x_event_loop

and

http://cppcms.com/cppcms_ref/latest/classcppcms_1_1service.html#a29410e26d78c56c3f22389db5828cd0c

but still have no idea how. Helps will be greatly appreciated.

Regards,
CN
