[−][src]Struct sys_util::SignalFd
A safe wrapper around a Linux signalfd (man 2 signalfd).
A signalfd can be used for non-synchronous signals (such as SIGCHLD) so that signals can be processed without the use of a signal handler.
Methods
impl SignalFd[src]
pub fn new(signal: c_int) -> Result<SignalFd, Error>[src]
Creates a new SignalFd for the given signal, blocking the normal handler for the signal as well. Since we mask out the normal handler, this is a risky operation - signal masking will persist across fork and even exec so the user of SignalFd should think long and hard about when to mask signals.
pub fn read(&self) -> Result<Option<signalfd_siginfo>, Error>[src]
Read a siginfo struct from the signalfd, if available.
