thanks very much for your support!!! i've understood that code, but however when i run it , i don't really see some difference, the server keeps in listening mode, blocking the execution of the rest of the code : i've added two simple line to print something on the console, and what i want is execute the server,that it keeps open in background but inmediatly execute too the printf code lines. main fuction would be : . . . . int main() { try { boost::asio::io_service io_service; tcp_server server(io_service); io_service.run(); printf("Writting a line 1 \n"); sleep(5); printf("Writting a line 2 \n"); } catch (std::exception& e) { std::cerr << e.what() << std::endl; } return 0; } 2009/11/9 Maxime van Noppen

Hi, i need to use a server inside of other code application, i take the example from

http://www.boost.org/doc/libs/1_40_0/doc/html/boost_asio/tutorial/tutdaytime...

...

and it works but the server stay in listening mode and there is other code after that i'd like continue executing, is possible tu run the server let's say like in a background mode?

Hi,

You should look to how asynchronous operations work :

io_service.run(); printf("Writting a line 1 \n");

The io_service can't exit the run command until all the work is complete. You need to put the io_service.run() into its own thread if you want to still execute things in main. boost::thread runningService(boost::bind(&boost::asio::io_service::run, io_service)); printf("Writting a line 1 \n"); sleep(5); printf("Writting a line 2 \n"); runningService.join(); This will allow you to continue and execute code in your main function. The problem you'll run into is trying to close the thread properly. I used the HTTP Server 2 example to create a class that ran my process but responded to an outside event to signal the class to stop processing. http://www.boost.org/doc/libs/1_40_0/doc/html/boost_asio/example/http/server...
