#[repr(transparent)]pub struct PollFd { /* fields omitted */ }

[−] Expand description

This is a wrapper around libc::pollfd.

It’s meant to be used as an argument to the poll and ppoll functions to specify the events of interest for a specific file descriptor.

After a call to poll or ppoll, the events that occured can be retrieved by calling revents() on the PollFd.

Implementations

impl PollFd[−]

pub fn new(fd: RawFd, events: PollFlags) -> PollFd[−]

Creates a new PollFd specifying the events of interest for a given file descriptor.

pub fn revents(self) -> Option<PollFlags>[−]

Returns the events that occured in the last call to poll or ppoll.
