WindowsKeyControlBlock

vmi::os::windows

Struct WindowsKeyControlBlock 

Source 
pub struct WindowsKeyControlBlock<'a, Driver>
where
    Driver: VmiRead,
    <Driver as VmiDriver>::Architecture: ArchAdapter<Driver>,
{ /* private fields */ }
Available on crate feature os-windows only.
Expand description

A Windows registry key control block.

A registry key in the kernel mode registry cache. It helps the Configuration Manager manage registry keys efficiently by avoiding redundant registry lookups.

§Implementation Details

Corresponds to _CM_KEY_CONTROL_BLOCK.

Implementations§

Source§

impl<'a, Driver> WindowsKeyControlBlock<'a, Driver>
where Driver: VmiRead, <Driver as VmiDriver>::Architecture: ArchAdapter<Driver>,

Source

pub fn new( vmi: VmiState<'a, WindowsOs<Driver>>, va: Va, ) -> WindowsKeyControlBlock<'a, Driver>

Creates a new Windows key control block.

Source

pub fn refcount(&self) -> Result<u64, VmiError>

Returns the reference count of the key control block.

§Implementation Details

Corresponds to _CM_KEY_CONTROL_BLOCK.RefCount.

Source

pub fn discarded(&self) -> Result<bool, VmiError>

Returns whether the key control block has been marked as discarded.

A discarded KCB no longer backs a live key node. The cache slot is kept alive only until its reference count drops to zero.

§Implementation Details

Corresponds to _CM_KEY_CONTROL_BLOCK.Discarded or _CM_KEY_CONTROL_BLOCK.Delete.

Source

pub fn parent( &self, ) -> Result<Option<WindowsKeyControlBlock<'a, Driver>>, VmiError>

Returns the parent key control block.

§Implementation Details

Corresponds to _CM_KEY_CONTROL_BLOCK.ParentKcb.

Source

pub fn name(&self) -> Result<String, VmiError>

Returns the name of the key.

§Implementation Details

Corresponds to _CM_KEY_CONTROL_BLOCK.NameBlock. If the _CM_NAME_CONTROL_BLOCK.Compressed field is set, the name is read as an ASCII string. Otherwise, the name is read as a UTF-16 string.

Source

pub fn hive(&self) -> Result<Option<WindowsHive<'a, Driver>>, VmiError>

Returns the hive that owns this key control block.

§Implementation Details

Corresponds to _CM_KEY_CONTROL_BLOCK.KeyHive.

Source

pub fn key_node(&self) -> Result<Option<WindowsKeyNode<'a, Driver>>, VmiError>

Returns the key node backing this key control block.

§Implementation Details

Resolves _CM_KEY_CONTROL_BLOCK.KeyCell against _CM_KEY_CONTROL_BLOCK.KeyHive.
