Registry Data types

ConstantDescription
REG_BINARY Binary data in any form.
REG_DWORD 32-bit number.
REG_QWORD 64-bit number.
REG_DWORD_LITTLE_ENDIAN 32-bit number in little-endian format. This is equivalent to REG_DWORD.
In little-endian format, a multibyte value is stored in memory from the lowest byte (the "little end") to the highest byte. For example, the value 0x12345678 is stored as (0x78 0x56 0x34 0x12) in little-endian format.
REG_QWORD_LITTLE_ENDIAN A 64-bit number in little-endian format. This is equivalent to REG_QWORD.
REG_DWORD_BIG_ENDIAN 32-bit number in big-endian format.
In big-endian format, a multibyte value is stored in memory from the highest byte (the "big end") to the lowest byte. For example, the value 0x12345678 is stored as (0x12 0x34 0x56 0x78) in big-endian format.
REG_EXPAND_SZ Null-terminated string that contains unexpanded references to environment variables (for example, "%PATH%"). It will be a Unicode or ANSI string, depending on whether you use the Unicode or ANSI functions.
REG_LINK Unicode symbolic link.
REG_MULTI_SZ Array of null-terminated strings that are terminated by two null characters.
REG_NONE No defined value type.
REG_RESOURCE_LIST Device-driver resource list.
REG_SZ Null-terminated string. It will be a Unicode or ANSI string, depending on whether you use the Unicode or ANSI functions.
