Problem with MFP and bound member

[C++/Win32/WinXP/.NET7.0]
I'm trying to write a threading class for my socket library, and I get compiler errors every time I try to use a function pointer. This is the interface for the class:

Code:

class Threader : public ThreadABC {
public:
	typedef void (*pf) (void);
	Threader( void (*pf) (void) ) : pfunction(pf)
	{ 
		begin(); 
	}
private:
	void (*pfunction) (void);
	void ThreadProc() {
		pfunction();
	}
};

begin() calls the CreateThread Win32 function, which in turn calls ThreadProc() (this is to get around the Windows problem with calling a member function).

This is the implementation that I try to use to instantiate the class:

Code:

void (*pc) (void);
pc = &(PackConnections);
ConnectionPacker = new Threader( pc );

This code brings up the compiler error C2276:

Code:

error C2276: '&' : illegal operation on bound member function expression

This error message points to the second line in the implementation (pc = &(PackConnections);).

Does anybody have any ideas?

Thanks

Assuming the function is the correct prototype, then

pc = PackConnections;

I replaced

Code:

pc = &(PackConnections);

with

Code:

pc = (PackConnections);

and now I'm getting an even scarier error:

Code:

error C2440: '=' : cannot convert from 'void (__thiscall SockServer::* )(void)' to 'void (__cdecl *)(void)'

I'm not even sure what that means...

(PackConnections is a method of SockServer, btw)

I've fixed the implementation with the following code:

Code:

void (SockServer::*pc) (void) = (&SockServer::PackConnections);
ConnectionPacker = new Threader( pc );

However, now the constructor definition seems to be the wrong type. I don't fully understand what this means:

Code:

error C2664: 'Threader::Threader(void (__cdecl *)(void))' : cannot convert parameter 1 from 
'void (__thiscall SockServer::* )(void)' to 'void (__cdecl *)(void)'

As you may recall, the constructor is as follows:

Code:

Threader( void (*pf) (void) )
{ 
	... 
}

What should the argument of the constructor be to be type-safe? Also, how should I cast so I can make the implementation type-safe?

Thanks
