First off, how can I have a program running two different pieces of code simultaneously?
Secondly, how could I (if possible) tell the program to run the two different pieces of code on different processors or cores if more than one core exists?
Thanks.
I don't know about messing around with cores but for multithreading you want to use CreateThread().
think about that peice of code for a moment and it will give you a decent answer for your first question, as far as the second no ideaCode:best_answer->subject();
The means of doing this are system dependent. Generally, the notion is to use a thread of execution that runs a particular function. The means of creating a thread vary between systems. For example, CreateThread() under the win32 API, under posix the function to create a thread is pthread_create(). Under most versions of unix, processes are actually fairly lightweight, so it may be better to fork() a copy of the current process, and have the child process run different code [the return value from fork() can be used to detect if the current process is the parent or the child].Quote:

There is also a function SetProcessAffinityMask() to set processors that a process is allowed to run on.
Heres a Multithreading tutorial
I would also suggest the Boost.Thread library which offers a exception-safe portable solution.
Alright, Ill try it out.
