winrt::guid-Struktur (C++/WinRT)
Stellt einen global eindeutigen Bezeichner (GLOBALLYD) dar.
Weitere Informationen und Codebeispiele finden Sie unter Interoperabilität mit der GUID-Struktur der ABI.
Syntax
struct guid
{
public:
uint32_t Data1;
uint16_t Data2;
uint16_t Data3;
uint8_t Data4[8];
guid() noexcept = default;
constexpr guid(uint32_t const Data1, uint16_t const Data2, uint16_t const Data3, std::array<uint8_t, 8> const& Data4) noexcept;
#ifdef WINRT_IMPL_IUNKNOWN_DEFINED
constexpr guid(GUID const& value) noexcept;
operator GUID const&() const noexcept;
#endif
constexpr explicit guid(std::string_view const value);
constexpr explicit guid(std::wstring_view const value);
};
inline bool operator==(guid const& left, guid const& right) noexcept;
inline bool operator!=(guid const& left, guid const& right) noexcept;
inline bool operator<(guid const& left, guid const& right) noexcept;
