Question

I want to write a simple server application that will take commands from a client application and run those commands in separate threads.

I was looking at the server class in dlib. Does anyone have experience using this? How does it compare to using Boost’s Asio?

• Example of server in dlib
• Examples of client/server in Boost Asio

Boost Asio will do this quite easily. Have a look at the examples in the Highscore tutorial, which shows how to use Boost for asynchronous input/output with multithreading.

#include <boost/asio.hpp> 
#include <boost/thread.hpp> 
#include <iostream> 

void handler1(const boost::system::error_code &ec) 
{ 
  std::cout << "5 s." << std::endl; 
} 

void handler2(const boost::system::error_code &ec) 
{ 
  std::cout << "5 s." << std::endl; 
} 

boost::asio::io_service io_service; 

void run() 
{ 
  io_service.run(); 
} 

int main() 
{ 
  boost::asio::deadline_timer timer1(io_service, boost::posix_time::seconds(5)); 
  timer1.async_wait(handler1); 
  boost::asio::deadline_timer timer2(io_service, boost::posix_time::seconds(5)); 
  timer2.async_wait(handler2); 
  boost::thread thread1(run); 
  boost::thread thread2(run); 
  thread1.join(); 
  thread2.join(); 
}
