Struct kernel::mm::virt::Area

source · [−]

pub struct Area { /* private fields */ }

Expand description

A wrapper for the kernel’s struct vm_area_struct.

It represents an area of virtual memory.

Invariants

vma is always non-null and valid.

Implementations

source

impl Area

source

pub fn flags(&self) -> usize

Returns the flags associated with the virtual memory area.

The possible flags are a combination of the constants in flags.

source

pub fn set_flags(&mut self, flags: usize)

Sets the flags associated with the virtual memory area.

The possible flags are a combination of the constants in flags.

source

pub fn start(&self) -> usize

Returns the start address of the virtual memory area.

source

pub fn end(&self) -> usize

Returns the end address of the virtual memory area.

source

pub fn insert_page(&mut self, address: usize, page: &Pages<0>) -> Result

Maps a single page at the given address within the virtual memory area.
