Feature gate: #![feature(unix_send_signal)]

This is a tracking issue for API to send a signal to a child process via libc kill.

Public API

// std::os::unix::process

pub trait ChildExt {
    fn send_signal(&self, signal: i32) -> Result<()>;
}

impl ChildExt for std::process::Child { /* ... */ }

Steps / History

(Remember to update the S-tracking-* label when checking boxes.)

• ACP: Add interrupt function to std::process::Child libs-team#97
• Incomplete implementation Added interrupt function for std::process::Child #101387
• Implementation: Implement send_signal for unix child processes #141990
• Final comment period (FCP)¹
• Stabilization PR

Unresolved Questions

• Should the signal be an i32 or an enum? Should we provide some SIG* constants so the user doesn't have to depend on libc? See discussion at the ACP Add interrupt function to std::process::Child libs-team#97
• Is there some reason our preexisting internal implementation took &mut? See discussion at Implement send_signal for unix child processes #141990.
