// STDMETHOD uses COM_DECLSPEC_NOTHROW, but STDMETHODIMP does not. This leads to attribute mismatch
15
// between interfaces and implementations which produces warnings. In theory a COM component should
16
// never throw a c++ exception, but COM_DECLSPEC_NOTHROW allows tweaking that (as it may be useful
17
// for internal only implementations within a single project). The behavior of the attribute nothrow
18
// and the keyword noexcept are slightly different, so use COM_DECLSPEC_NOTHROW instead of noexcept.
19
// Older interfaces like IUnknown and IStream do not currently specify COM_DECLSPEC_NOTHROW, but it
20
// is not harmful to mark the implementation more exception strict than the interface.
