Struct udt::Epoll

pub struct Epoll {
    // some fields omitted
}

Used with the epoll* methods of a UDTSocket

Methods

impl Epoll

fn create() -> Result<Epoll, UdtError>

Creates a new Epoll object

fn add_usock(&mut self, socket: &UdtSocket, events: Option<EpollEvents>) -> Result<(), UdtError>

Adds a UdtSocket to an epoll

events can be any combination of UDT_EPOLL_IN, UDT_EPOLL_OUT, and UDT_EPOLL_ERR

fn remove_usock(&mut self, socket: &UdtSocket) -> Result<(), UdtError>

Removes a UdtSocket from an epoll

If the socket isn't part of the epoll, there is no error

fn wait(&mut self, timeout: i64, write: bool) -> Result<(Vec<UdtSocket>, Vec<UdtSocket>), UdtError>

Wait for events

Timeout is in milliseconds. If negative, wait forever. If zero, return immediately.

If write is false, the list of sockets for writing will always be null.

Returns

A tuple of sockets to be read and sockets to be written (or have exceptions)
