Multithreading

i need some code that allows me to use the CreateThread API function to spin off a new thread and run a function. i also need to know how i should properly declasre the function if it has to be different from normal. i also need to know how to close the thread and delete it.

I hear that you should use beginthread instead of CreateThread(). There should be info in the MSDN. I will try to give an example later, if you still need it.

cheers zaei, will have a look their in a tick. i have been working on server stuff recently as you may have noticed :D

i probably will need a demo coz im that constipated.

From my current code:

Code:

---

        class thread {
        public:
                thread(void (__cdecl *func)(void*) = thread::run, void *param = 0);

                static void sleep(uint32 milliseconds);

        private:
                static void run(void *param);

                uint32 m_thread;
        };

---

Code:

---

        thread::thread(void (__cdecl *func)(void*), void *param) {
                m_thread = _beginthread(func, 0, param);
                if(!m_thread) {
                        throw std::runtime_error("Could not create thread");
                }
        }

        void thread::run(void *param) {
                _endthread(); // exit
        }

        void thread::sleep(uint32 milliseconds) {
                return Sleep(milliseconds);
        }

lol, i got this going now but i used a CreateThread version which works.

If you use anything from the Standard Library (whether C or C++) you need to use _beginthread (or _beginthreadex) otherwise you'll get a memory leak.

Yupper =).

ok i changed it to _beginthread and to work like you have done in your code, the only problem is that it cannot find the functions.

i added process.h to includes but still no luck, i looked in the h and saw it had #if defined _MT so i then added #define _MT before the include and it says it cannot link to _beginthread whereas endthread works fine.

Take out your #define _MT, and in Project Settings you need to change it from Single threaded to Multithreaded (under C++ I think).

You'll need to change it for both Debug and Release.

lol, i changed the threading code to what you said, then i changed the project settings and now the server dont work properly lol
