Struct leftwm_core::utils::child_process::Children

pub struct Children { /* private fields */ }

A struct managing children processes.

The reap method could be called at any place the user wants to. register_child_hook provides a hook that sets a flag. User may use the flag to do a epoch-based reaping.
