Threading from inside your class?

Hey, quick question for y'all. I can't seem to figure out how to create a thread within a class using a function in that class.

ie: if my class TestIt has two functions: One private called collectdata, one public called collect. In my program I want collect() to call _beginthread (or createthread or whatever will work) with collectdata as the function. Is it even possible?

you can pass a pointer to the class into beginthread() with a static or global thread function. I prefer static on the class you're passing in and then immediately calling a method that isn't static.

Care to elaborate? :) maybe with some example code?

Thanks.

Code:

#include <windows.h>

#include <iostream>
using namespace std;


class FooBar
{
    HANDLE m_hthread;
    DWORD m_threadid;

    // static method for thread entry point
    static DWORD WINAPI ThreadProc(LPVOID lpv)
    {
        return reinterpret_cast<FooBar*>(lpv)->ThreadMethod();
    }//ThreadProc

    // member function called by static thread entry point
    DWORD ThreadMethod()
    {
        for (int n = 0; n < 5; n++)
        {
            cout << "Look at me! I'm a thread!!" << endl << flush;
            ::Sleep(1000);
        }//for

        return 0;
    }//ThreadMethod
public:
    FooBar() : m_hthread(NULL), m_threadid(0) {}
    ~FooBar()
    {
        // stop thread here if need be
        if (m_hthread != NULL)
        {
            ::CloseHandle(m_hthread);
        }//if
    }//destructor

    // start the thread running
    bool StartThread()
    {
        m_hthread = ::CreateThread(NULL, 0, FooBar::ThreadProc,
                                  reinterpret_cast<void*>(this),
                                  0, &m_threadid);
        return m_hthread != NULL;
    }//StartThread

    // wait for the thread to exit
    bool Join()
    {
        if (m_hthread == NULL)
            return false;
        return ::WaitForSingleObject(m_hthread, INFINITE) == WAIT_OBJECT_0;
    }//Join
};//FooBar

int main()
{
    FooBar fb;

    fb.StartThread();

    // wait for the thread to exit
    fb.Join();

    return 0;
}//main
