pub struct GlobalDescriptorTableRegister { pub limit: u16, pub address: usize, }
Available on x86 or x86-64 only.
Expand description

GDTR: Points to the memory range of the global descriptor table (GDT).

Fields§

§limit: u16

The inclusive maximum address offset (i.e., size - 1) of the descriptor table.

§address: usize

Base address of the descriptor table

Implementations§

Retrieve the current value of this register

Update the register to the given value.

Safety

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

Update the global descriptor table pointer and all segment registers.
