KEY_VALUE_BASIC_INFORMATION structure
The KEY_VALUE_BASIC_INFORMATION structure defines a subset of the full information available for a value entry of a registry key.
Syntax
typedef struct _KEY_VALUE_BASIC_INFORMATION { ULONG TitleIndex; ULONG Type; ULONG NameLength; WCHAR Name[1]; } KEY_VALUE_BASIC_INFORMATION, *PKEY_VALUE_BASIC_INFORMATION;
Members
- TitleIndex
-
Device and intermediate drivers should ignore this member.
- Type
-
Specifies the system-defined type for the value entry in the registry key, 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 null-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 null-terminated strings, terminated by another zero
REG_NONE
Data with no particular type
REG_SZ
A null-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
-
Specifies the size in bytes of the following value entry name.
- Name
-
A string of Unicode characters naming a value entry of the key.
Remarks
A kernel-mode driver can obtain a KEY_VALUE_BASIC_INFORMATION that describes a registry key by calling the ZwQueryValueKey or ZwEnumerateValueKey routine.
