Nothing. Your done. :-) bind takes a pointer to a function (among other
things) as the first parameter. It then calls that function with the
parameters you specify. You use _1, etc for parameters that are input to
bind. In your case:

std::find_if(begin, end, boost::bind(std::equal<std::string>,
name_to_find, _1)));
