Function send_rt_to_group 

pub fn send_rt_to_group(
    signal: impl Into<Option<u32>>,
    pid: impl Into<u32>,
) -> Result<()>

Available on Unix and crate feature signals only.

Sends the specified real-time signal to the specified process. If the specified signal is None, no signal is sent and only a privilege check is performed instead.

Example

use interprocess::os::unix::signal::{self, SignalType};
use std::process;

// Send a real-timne signal 0 to the process group of the calling process.
signal::send_rt(0_u32, 0_u32)?;
