[−][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.
Implementations
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.
