[−][src]Struct nix::poll::PollFd
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
.
Methods
impl PollFd
[src]
pub fn new(fd: RawFd, events: PollFlags) -> PollFd
[src]
Creates a new PollFd
specifying the events of interest
for a given file descriptor.
pub fn revents(&self) -> Option<PollFlags>
[src]
Returns the events that occured in the last call to poll
or ppoll
.
