winrt:: guid 結構 (c + +/WinRT)

代表 (GUID) 的全域唯一識別碼。

如需詳細資訊和程式碼範例,請參閱 與 ABI 的 GUID 結構互操作。

語法

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;
