C function needs to call a member function

[manu1001]

I've an old C function that calls a function pointed by a global function pointer. How do I get it to call a member function of a class object determined at run-time. It'll be complied in a C++ project of course.
My main motive is reusability here. So I don't want to change the C function.

Its something like this:

 
void (*foo)(int);
 
class coo
{
  public:
        void func(int x){ ; }
};
 
void cfunc()
{
  foo(10);  
}
