| 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. |
