pub enum LocalDescriptorTableRegister {}
Available on x86 or x86-64 only.
Expand description

LDTR: Contains a Selector referencing a SegmentDescriptor that points to the the local descriptor table (LDT).

Note that this type cannot be instantiated. It simply serves as a namespace for the get and set methods, which work on a Selector instance.

Implementations§

source§

impl LocalDescriptorTableRegister

source

pub fn get() -> Selector

Retrieve the current value of this register

source

pub unsafe fn set(selector: Selector)

Update the register with the value in this struct.

The value must point to an entry in the global descriptor table (local == false) with the SystemDescriptorType::LocalDescriptorTable type.

§Safety

This register fundamentally affects memory accesses and can have an impact on memory safety.

source

pub unsafe fn current_descriptor() -> *const SegmentDescriptor

Get a pointer to the SegmentDescriptor for the currently-loaded local descriptor table, using the value of this register.

§Safety

The LDTR must not loaded with a selector for a valid LDR segment descriptor. The returned pointer is only valid until the LDTR is modified.
