How to use C++ standard smart pointers with Windows HANDLEs?

Question

I was wondering if there is a way to use unique_ptr with Windows HANDLEs?

I was thinking to replace the std::default_delete with s

Answer 1

You can typedef your unique_ptr with a custom deleter

struct handle_deleter
{
    void operator()(void* handle)
    {
        if(handle != nullptr)
            CloseHandle(handle);
    }
};

typedef std::unique_ptr UniqueHandle_t;
UniqueHandle_t ptr(CreateFile(...));
