Passing a member method as a function pointer?

I''ve already googled and checked function-pointer.org. Now that that''s out of the way, to the question. Is it possible to pass a member function (C++) to a C-style function that has a C-style function pointer as a parameter. Here is some code to simplify: 
void SetFP((int (*fp)(void *));


class foo
{
public:
   int bar(void *);

   void foobar() { SetFP(bar); }  // How can I do this?

}
So far I''ve tried a lot of different syntax approaches and none have worked. Has anyone else encountered this problem or knows the answer to it?

Thanks for the quick reply. I''ll check out boost, didn''t know they had such features.

Also, I figured it out in another way, by using a static method that calls a private method through a void pointer. It''s a bit messy, but since the library C function I am using uses a pointer to a function that takes a void pointer. Thus I pass the static member function, in it I convert explicitly the pointer to a this-type and call the member method.
