# waitpid-any: Wait for any PID

[waitpid(2)] can only be used to wait for direct child processes, or it fails
immediately.

This crate provides a extension to wait for the exit of any process, not
necessarily child processes. Due to platform limitations, the exit reason and
status codes still cannot be retrieved.
