KEY_VALUE_BASIC_INFORMATION defines a subset of the full information available for a value entry of a registry key.

Members

TitleIndex

Device and intermediate drivers should ignore this member.

Type

The system-defined type for the registry value in the Data member, which is one of the following:

REG_XXX Type	Value
REG_BINARY	Binary data in any form
REG_DWORD	A 4-byte numerical value
REG_DWORD_LITTLE_ENDIAN	A 4-byte numerical value whose least significant byte is at the lowest address
REG_DWORD_BIG_ENDIAN	A 4-byte numerical value whose least significant byte is at the highest address
REG_EXPAND_SZ	A zero-terminated Unicode string, containing unexpanded references to environment variables, such as “%PATH%”
REG_LINK	A Unicode string naming a symbolic link. This type is irrelevant to device and intermediate drivers
REG_MULTI_SZ	An array of zero-terminated strings, terminated by another zero
REG_NONE	Data with no particular type
REG_SZ	A zero-terminated Unicode string
REG_RESOURCE_LIST	A device driver’s list of hardware resources, used by the driver or one of the physical devices it controls, in the \ResourceMap tree
REG_RESOURCE _REQUIREMENTS_LIST	A device driver’s list of possible hardware resources it or one of the physical devices it controls can use, from which the system writes a subset into the \ResourceMap tree
REG_FULL_RESOURCE _DESCRIPTOR	A list of hardware resources that a physical device is using, detected and written into the \HardwareDescription tree by the system

NameLength

The size in bytes of the following value entry name, including the zero-terminating character.

Name

A zero-terminated Unicode string naming a value entry of the key.
