Learning Linux processes termination in Rust

• Cloned/forked Initially from Ivan Velichko's Repo

The project covers the following scenarios:

• awaiting a child process termination;
• awaiting a grandchild process termination;
• catching the parent process termination.
• using pipes to communicate between 2 different childs
• using prctl() to make parent or grandparent sub-reaper of (grand)child, if first child process (Parent of grand parent) dies.

Usage

cargo build

# wait for the child termination
cargo run --bin wait_block

# wait for the child termination while busy looping
cargo run --bin wait_busy

# wait for the child termination signaled to you
cargo run --bin wait_signal

# test Linux CHILD_SUBREAPER feature
cargo run --bin subreaper

# put all things together
cargo run --bin combined
