The value of ^ variables in C ++ / CX

I just returned to C ++ for a game-related project for Windows 8 / RT after many years of absence in favor of C #.

Working with the generated project project skeleton I came across method signatures, as shown below. Can someone enlighten me what should do?

Concurrency::task<Platform::Array<byte>^> ReadDataAsync(Platform::String^ filename)

In C ++ / CX, a T^ is a handle to an object T This is an efficient smart pointer that owns a reference to an object pointing to an object, with some additional bonus features provided by the compiler.

Apparently, it is called the handle-to-object operator.

The handle-to-object ^ operator is known as a hat and is basically a C ++ smart pointer. The memory that it points to is automatically destroyed when the last hat goes out of scope or is explicitly set to nullptr.

According to: https://msdn.microsoft.com/en-us/library/hh699870.aspx . (From the "Memory Management" section of this page.

The ^ character is an object handle.

For example, String^ s; declares a handle to the object 'String'.
