Struct nix::poll::PollFd

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

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.
