Going back to the original topic of the thread (no pun intended here), I
(may be wrong in this) thought that the following would work:

class A {
public:
	void *threadfunc();
};

typedef void *(*threadfunc_t)(void *);

int func(void) {
	A a;
	:
	:
	pthread_create(&id, NULL, (threadfunc_t)(a->threadfunc), &a);
	:
	:
}

I haven't even entered the code above into an editor nor come close to
compiling it, but as I the instance pointer (iirc) was passed to a
non-static member function as an implicit (first) parameter, my thoughts
were that the above *should* work (with a little tweaking, perhaps)?

I could be totally wrong on several issues, but that was my
understanding of things.
