REG_SET_KEY_SECURITY_INFORMATION structure (wdm.h)
The REG_SET_KEY_SECURITY_INFORMATION structure specifies security information for a registry key object.
Syntax
typedef struct _REG_SET_KEY_SECURITY_INFORMATION {
PVOID Object;
PSECURITY_INFORMATION SecurityInformation;
PSECURITY_DESCRIPTOR SecurityDescriptor;
PVOID CallContext;
PVOID ObjectContext;
PVOID Reserved;
} REG_SET_KEY_SECURITY_INFORMATION, *PREG_SET_KEY_SECURITY_INFORMATION;
Members
Object
A pointer to the registry key object for the key whose security information is being set.
SecurityInformation
A pointer to a SECURITY_INFORMATION-typed variable that identifies the type of security information that is being set.
SecurityDescriptor
A pointer to a SECURITY_DESCRIPTOR structure that contains security information for the key object.
CallContext
Optional driver-defined context information that the driver's RegistryCallback routine can supply. This member is defined for Windows Vista and later versions of the Windows operating system.
ObjectContext
A pointer to driver-defined context information that the driver has associated with a registry object by calling CmSetCallbackObjectContext. This member is defined for Windows Vista and later versions of the Windows operating system.
Reserved
This member is reserved for future use. This member is defined for Windows Vista and later versions of the Windows operating system.
Remarks
The system passes the REG_SET_KEY_SECURITY_INFORMATION structure to the RegistryCallback routine every time a thread attempts to set a key's security information—for example, when a driver calls ZwSetSecurityObject.
