Struct LinuxVmAreaStruct

pub struct LinuxVmAreaStruct<'a, Driver>
where
    Driver: VmiDriver,
    Driver::Architecture: Architecture + ArchAdapter<Driver>,
{ /* private fields */ }

A Linux VM area struct.

A vm_area_struct is a structure that represents a memory region (Virtual Memory Area, or VMA) in a process’s address space.

Implementation Details

Corresponds to vm_area_struct.

Implementations

impl<'a, Driver> LinuxVmAreaStruct<'a, Driver>

where Driver: VmiDriver, Driver::Architecture: Architecture + ArchAdapter<Driver>,

pub fn new(vmi: VmiState<'a, Driver, LinuxOs<Driver>>, vad: Va) -> Self

Creates a new VM area struct.

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

Returns the flags of the memory region.

The flags are a bitmask that represent the memory region’s permissions and other attributes.

Notes

This value is cached after the first read.

Implementation Details

Corresponds to vm_area_struct.vm_flags.
