stl binary_search with linked list

[Sno Kart]

I have a class associated with a linked list and would like to implement the binary_search algorithm. How?

long s;
cout<<"Enter item to serach"<<endl;
cin>>s;

 for(iter2 = form2List.begin();iter2 != form2List.end(); iter2++)
        {
binary_search(form2List.front(),form2List.end(),(*iter2).var1,s);
        }

thanks..
