.. function:: CopyComPointer(src, dst)

Copies a COM pointer from *src* to *dst* and returns the Windows specific
:c:type:`!HRESULT` value.

If *src* is not ``NULL``, its ``AddRef`` method is called, incrementing the
reference count.

In contrast, even if *dst* is not ``NULL``, its reference count will not be
decremented before assigning the new value. You need to call its ``Release``
to free it appropriately.
