I have a vector of

class Landmark { public: std::string const& getName() const; ... };

I want to do a find_if for a name that I have.

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

What do I put for the ??? ?

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)));

But I have to compare name_to_find to the result of _1.getName() don't I? ----------------------------------------------------------------------- DISCLAIMER: Information contained in this message and/or attachment(s) may contain confidential information of Zetec, Inc.
