[][src]Struct pakr_mio_signalfd::SignalFd

pub struct SignalFd { /* fields omitted */ }

SignalFd can be used to create mio-compatible signal handlers.


impl SignalFd[src]

pub fn new(sigset: &SigSet) -> Result<Self>[src]

Create a new signalfd watching the given signal set.

pub fn read(&self) -> Result<Option<SigInfo>>[src]

Acknowledges received signal. It must be called after catching signal to acknowlege that signal. If you don't read, the same signal is re-issued on the next poll iteration.


  • Ok(None) - if there was no signal waiting (SignalFd is opened as NONBLOCK)
  • Ok(Some(SigInfo)) - if there was pending signal information
  • Err(...) - if there was error reading signal information
