Struct Epoll

pub struct Epoll { /* private fields */ }

Implementations

impl Epoll

pub fn new() -> Arc<AtomicRefCell<Self>>

pub fn status(&self) -> FileStatus

pub fn set_status(&mut self, status: FileStatus)

pub fn mode(&self) -> FileMode

pub fn has_open_file(&self) -> bool

pub fn supports_sa_restart(&self) -> bool

pub fn set_has_open_file(&mut self, val: bool)

pub fn close( &mut self, cb_queue: &mut CallbackQueue, ) -> Result<(), SyscallError>

pub fn readv( &mut self, _iovs: &[IoVec], _offset: Option<off_t>, _flags: c_int, _mem: &mut MemoryManager, _cb_queue: &mut CallbackQueue, ) -> Result<ssize_t, SyscallError>

pub fn writev( &mut self, _iovs: &[IoVec], _offset: Option<off_t>, _flags: c_int, _mem: &mut MemoryManager, _cb_queue: &mut CallbackQueue, ) -> Result<ssize_t, SyscallError>

pub fn ioctl( &mut self, _request: IoctlRequest, _arg_ptr: ForeignPtr<()>, _mem: &mut MemoryManager, ) -> SyscallResult

pub fn stat(&self) -> Result<stat, SyscallError>

pub fn ctl( &mut self, op: EpollCtlOp, target_fd: i32, target_file: File, events: EpollEvents, data: u64, weak_self: Weak<AtomicRefCell<Epoll>>, cb_queue: &mut CallbackQueue, ) -> Result<(), Errno>

Executes an epoll control operation on the target file.

We think this panics if target_file is an instance of this epoll object due to recursive mutable borrows (but it does not panic due to a check+panic).

pub fn add_listener( &mut self, monitoring_state: FileState, monitoring_signals: FileSignals, filter: StateListenerFilter, notify_fn: impl Fn(FileState, FileState, FileSignals, &mut CallbackQueue) + Send + Sync + 'static, ) -> StateListenHandle

pub fn add_legacy_listener(&mut self, ptr: HostTreePointer<StatusListener>)

pub fn remove_legacy_listener(&mut self, ptr: *mut StatusListener)

pub fn state(&self) -> FileState

pub fn has_ready_events(&self) -> bool

pub fn collect_ready_events( &mut self, cb_queue: &mut CallbackQueue, max_events: u32, ) -> Vec<(EpollEvents, u64)>
