min

template<class T>
    const T& min(const T& x, const T& y);
template<class T, class Pred>
    const T& min(const T& x, const T& y, Pred pr);

The first template function returns y if y < x. Otherwise it returns x. T need supply only a single-argument constructor and a destructor.

The second template function behaves the same, except that it replaces operator<(X, Y) with pr(X, Y).

Microsoft-Specific:
To avoid conflicts with min and max in WINDEF.H, use _MIN and _MAX instead. These macros evaluate to _cpp_min and _cpp_max, respectively.
