Function nix::poll::ppoll

pub fn ppoll(
    fds: &mut [PollFd], 
    timeout: TimeSpec, 
    sigmask: SigSet
) -> Result<c_int>

ppoll() allows an application to safely wait until either a file descriptor becomes ready or until a signal is caught. (poll(2))

ppoll behaves like poll, but let you specify what signals may interrupt it with the sigmask argument.
