Re: Throwing error is potentially buggy

Only if you don't catch it. See sample below.


Derive from std::exception, and throw those

e.g.:

class receive_error : public std::exception { ... };
class send_error : public std::exception { ... };
class processing_error : public std::exception { ... };

initialize();
while (true) {
   try {
     Message msg,out;
     receive(msg);
     process(msg,out);
     send(out);
   }
   catch (receive_error& e) {
     // receive() barfed
   }
   catch (processing_error& e) {
     // process() barfed
   }
   catch (send_error& e) {
     // send() barfed
   }
   // other exceptions propagate out
}
