signal_hook::iterator::exfiltrator::origin

Struct WithOrigin

Source
pub struct WithOrigin(/* private fields */);
Available on non-Windows and crate feature iterator and crate feature extended-siginfo only.
Expand description

The Exfiltrator that produces Origin of signals.

§Examples

// Subscribe to SIGUSR1, with information about the process.
let mut signals = SignalsInfo::<WithOrigin>::new(&[SIGUSR1])?;

// Send a signal to ourselves.
let my_pid = unsafe { libc::getpid() };
unsafe { libc::kill(my_pid, SIGUSR1) };

// Grab the signal and look into the details.
let received = signals.wait().next().unwrap();

assert_eq!(SIGUSR1, received.signal);
assert_eq!(my_pid, received.process.unwrap().pid);
