Required Methods§

Source

fn send_signal(&self, signal: i32) -> Result<()>

Send the specified signal to the child process.

The signal numbers are best obtained from the libc crate.

If the child process is known to have finished (due to e.g. a previous call to wait or poll), this will do nothing and return Ok.
