public template<typename FunctionT>
inline callback_wrapper & except(FunctionT const & f) 		Sets an error callback.
public template<typename FunctionT>
inline callback_wrapper & except(FunctionT && f) 		Sets an error callback.

inline callback_wrapper & except(FunctionT const & f)

Sets an error callback.

public template<typename FunctionT>
