| | If you want to know more about compiling, linking and programming I really advice you to use g++ ( minGW in windows ) and a simple text editor. Linux is better than Windows in this sense ofcourse if you mind using it. |
| | You can do it creating a new thread, process or simply using a callback function. I don't use windows though, to create a thread in Linux pthread_create(), to create a new process use fork(). Use function pointers to handle callbacks. |
