  PVOID           CallContext;
  PVOID           ObjectContext;

} REG_REPLACE_KEY_INFORMATION, *PREG_REPLACE_KEY_INFORMATION;

Members

Object

A pointer to a registry key object for the key whose metadata is about to be replaced.

OldFileName

The name of the file that receives a backup copy of the registry information being replaced.

NewFileName

The name of the file with the registry information. This file is typically created by using the RegSaveKey function.

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

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 this structure to the RegistryCallback routine every time a thread attempts to replace the metadata for a key.
