Member Functions as Thread Procs

[johnnie2]

Is there any way to specify a class member function as the thread procedure in calls such as beginthreadex() or CreateThread()?

Yes, but they must be static member functions............

#include <iostream>
#include <string>
#include <windows.h>

class foobar{
public:
	static DWORD WINAPI ThreadProc(LPVOID);
};

DWORD WINAPI foobar::ThreadProc(LPVOID lpv){
	std::cout << static_cast<char*>(lpv);
	return 0;
}


int main(void){

	

	DWORD dwDummy;
	HANDLE hHand;
	char str[] = "Hello World";

	hHand = CreateThread(0,0,&foobar::ThreadProc,
		static_cast<LPVOID>(str),0,&dwDummy);     
		
	WaitForSingleObject(hHand,INFINITE);

};

Thanks for the response. I'm guessing there is absolutely no way to accomplish this with non-static member functions?

Right.
