I'm trying to bind a member function as a Win32 thread function type so I can pass it to CreateThread. From what I understand from the boost.bind doc, it should be done like this: struct MsThread { DWORD WINAPI Mediary(LPVOID); DWORD _threadId; }; MsThread thread; CreateThread(NULL, 0, boost::bind< DWORD WINAPI >(&MsThread::Mediary, &thread, _1), 0, &thread._threadId); However, it gives me errors. I'm using MinGW g++ 3.2.3 WinXP. Thanks for any help. [edited by - dcosborn on January 27, 2004 8:18:46 AM]

CreateThread expects a plain C function pointer.
boost::bind returns a boost::function object.

No cigar.

boost::thread will happily accept boost::function (and other) objects

I give it 8.5/10

8 because it''s awesome, and an extra 0.5 because it''s fairly small.

Why dont you use boosts threads aswell?

class Class
{
public:
void run();
}

Class obj;

boost::thread t(boost::bind(&Class::memberfunc, &obj));

or:

void run();

boost::thread t(run);

Much nicer, and portable too!
