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;
