Create thread is not accepting the member function

Question

I am trying to create a class for network programming. This will create a general purpose socket with thread.

But when I tried to crete the thread using createthread

There's an easy way to solve the problem.

Take a look at ThreadProc callback function:

    DWORD WINAPI ThreadProc(
      __in  LPVOID lpParameter
    );

And now at CreateThread function:

    HANDLE WINAPI CreateThread(
      __in_opt   LPSECURITY_ATTRIBUTES lpThreadAttributes,
      __in       SIZE_T dwStackSize,
      __in       LPTHREAD_START_ROUTINE lpStartAddress,
      __in_opt   LPVOID lpParameter,
      __in       DWORD dwCreationFlags,
      __out_opt  LPDWORD lpThreadId
    );

Use a static method as thread procedure, but call it from a member method, and pass the object pointer to it:

    #include 

    class MyClass {
     public:
      void CreateThreadForObject() {
        LPSECURITY_ATTRIBUTES security_attributes = 0;
        SIZE_T stack_size = 0;
        LPTHREAD_START_ROUTINE start_routine = &MyClass::ThreadProcForObject;
        LPVOID param = this;
        DWORD creation_flags = 0;
        LPDWORD thread_id = 0;
        CreateThread(security_attributes, stack_size, start_routine, param,
                     creation_flags, thread_id);
      }

     private:
      static DWORD WINAPI ThreadProcForObject(LPVOID param) {
        MyClass* instance = reinterpret_cast(param);
        if (!instance) return 1;
        // ...
        return 0;
      }
    };

Sorry, I just don't have enough time to write a good example. But I think you understand the way.
