    how to derive from class with templates

    Hi,
    How do i derive from the vector class?
    I wrote this but it is not correct for sure.

    Code:
    template <class T, class Allocator = allocator<T> > class DataBlock 
    : vector <T,Allocator >  {
    	//some more functions
    
    };
    thanks

    You don't, actually. vector is not designed to be derived from. If you want to add functionality, write free functions.
    All the buzzt!
