Hi All,

I wonder if it is possible to pass a member function to an extern function, i.g.

// external function
float ef(float (*f)(float), float x){
  float f;
  f= (*f)(x);
  return f;
}

class A {
  float x1;

public:

  float f1();
  float f2();
}

float f1(){
  float f;

  f=x1*x1;
  return f;
}

float f2(){

float f;

f= ef(f1, x); // gcc gives error

return f;
}
 ..........

Thanks in advance.
