I've got a node struct
struct Node{CString text, int id;};
in a sorted vector.
I'm wondering if there's a function in algorithm that will do a binary search of the vector and find an element.

If I'd like to know how a function written in like standard C++ library work (not just the MSDN description). I mean how does it allocate, manage, deallocate memory and return you the result. where or what do you need to know to understand that?
