Function Documentation

deleter_for()

template<typename Owned , typename Deleter >

auto mir::raii::deleter_for ( Owned *  owned, Deleter &&  deleter  ) -> std::unique_ptr<Owned, Deleter>

inline

Creates an RAII object from an owning pointer and deleter.

The returned object is a std::unique_ptr initialized with the pointer and deleter.

Parameters

owned	the object to take ownership of
deleter	called to finalize the owned object

paired_calls()

template<typename Creator , typename Deleter >

auto mir::raii::paired_calls ( Creator &&  creator, Deleter &&  deleter  ) -> std::unique_ptr<typename std::remove_reference<decltype(*creator())>::type, Deleter>

inline

Creates an RAII object from a creator and deleter.

If creator returns a pointer type then the returned object is a std::unique_ptr initialized with the pointer and deleter. Otherwise, the returned object calls creator on construction and deleter on destruction

Parameters

creator	called to initialize the returned object
deleter	called to finalize the returned object

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
