Struct nix::poll::PollFd [−][src]
#[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
.
