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

Just create some thread safe object that can keep the data you need (i.e. member functions that access it protected with mutexes/rw-locks).

Applications my_hello_world and chat are mounted under different application tree branches, How does my_hello_world acquire the reference of chat instance? I'ts good to know that cppcms::service::post() is not required in such case! Nevertheless, an example code demonstrating the usage of cppcms::service::post() would be greatly appreciated - just in case I will need to call it some other day!

Having contemplated for a while, I am trying to reply my first question as follows. Please correct me if I am wrong! The solution might be as simple as passing the reference of the asynchronous application object as a parameter to the synchronous application in interest like this: cppcms::service srv(argc,argv); booster::intrusive_ptr<chat> c=new chat(srv); srv.applications_pool().mount(cppcms::applications_factory<my_hello_world>(c)); service.applications_pool().mount(c); Regards, CN On Sat, Nov 23, 2013, at 11:02 AM, CN wrote: Applications my_hello_world and chat are mounted under different application tree branches, How does my_hello_world acquire the reference of chat instance?

Yes, this is one of the many ways. I would suggest to have some singleton keepig shared data Artyom Having contemplated for a while, I am trying to reply my first question as follows.
