Implementations

impl ProcessData

pub fn new( exe_path: String, aspace: Arc<Mutex<AddrSpace>>, signal_actions: Arc<Mutex<SignalActions>>, exit_signal: Option<Signo>, ) -> Self

Create a new ProcessData.

pub fn get_heap_bottom(&self) -> usize

Get the bottom address of the user heap.

pub fn set_heap_bottom(&self, bottom: usize)

Set the bottom address of the user heap.

pub fn get_heap_top(&self) -> usize

Get the top address of the user heap.

pub fn set_heap_top(&self, top: usize)
