Defined in header <memory>
template< class T, class... Args > unique_ptr<T> make_unique( Args&&... args );	(1)	(since C++14) (only for non-array types)
template< class T> unique_ptr<T> make_unique( std::size_t size );	(2)	(since C++14) (only for array types with unknown bound)
template< class T, class... Args > /* unspecified */ make_unique( Args&&... args ) = delete;	(3)	(since C++14) (only for array types with known bound)

Constructs an object of type T and wraps it in a std::unique_ptr.

1) Constructs a non-array type T. The arguments args are passed to the constructor of T. The function does not participate in the overload resolution if T is an array type. The function is equivalent to:

unique_ptr<T>(new T(std::forward<Args>(args)...))

2) Constructs an array of unknown bound T. The arguments args are passed to the constructor of T. The function does not participate in the overload resolution if T is an array type. The function is equivalent to:

unique_ptr<T>(new typename std::remove_extent<T>::type[size]())

3) Construction of arrays of known bound is disallowed.

Parameters

args	-	list of arguments with which an instance of T will be constructed.
size	-	the size of the array to construct

Return value

std::unique_ptr of an instance of type T.

Exceptions

Any exception thrown by the contructor of T. If an exception is thrown, this function has no effect.
