What does a colon mean after a function in a struct

Question

struct node
{
    int info;
    node* next; 
    node(int D, node *N)
    :  info(D),next(N)
    {  }
};
node* list;

In the above declaration of a linked list what does the following mean?

node(int D, node *N)
        :  info(D),next(N)
        {  }

This isn't [tag:c]. It's [tag:c++]. http://en.cppreference.com/w/cpp/language/initializer_list — StoryTeller - Unslander Monica, Dec 26 '16 at 06:47

It is the node constructor using initializer list to initialize its member variables.
