  16. Hi, 
  17.  
  18. the question is about member templates and virtual functions. I know these 
  19. are prohibited. However, what about the following example:
  20.  
  21. class Base
  22. {
  23.  virtual void f(int);
  24. };
  25.  
  26. class Derived : Base
  27. {
  28. template<class T> void f(T);
  29. };
  30.  
  31. Is this legal? If so, will the template function f(int) override 
  32. Base::f(int)? If so, when will it be instantiated? And, last but not least, 
  33. which section of the DWP handles this case? Thanks in advance.
  34.  
  35. Bye
  36.  
  37. Roman
