Detailed Description

A concept that describes C++ data types used for registry values.

The follwoing table shows which C++ types are used for which registry value types:

Registry Value Type	C++ Type
REG_DWORD	DWORD or std::uint32_t
REG_QWORD	std::uint64_t
REG_SZ	std::wstring or std::string
REG_EXPAND_SZ	std::wstring or std::string
REG_MULTI_SZ	std::vector<std::wstring> or std::vector<std::string>
REG_BINARY	xentara::utils::core::RawDataBlock or std::vector<std::byte>

Registry values of type REG_BINARY with the correct length can also be accessed using the C++ types DWORD, std::uint32_t, or std::uint64_t. DWORD and std::uint32_t can be used for data with a length of 4 bytes (32 bits), and std::uint64_t for REG_BINARY can be used for data with a length of 8 bytes (64 bits).
