found the thing... its not a book and C++ has no generics but
templates (for me both are the same, im no C++ programmer).

Now reading it again... The thing is that a quicksort in C can be fast
only if used for one single type (at least the comparision function)
while in C++ the template specialization makes the comparision
function work for a greater number of types, simplifying resulting
code...
