int setup_cgroup_environment (void );

🦋 DESCRIPTION 🦋

Okay so after you call this function, you gotta call cleanup_cgroup_environment once testing is complete — that's the vibe, don't skip it 💖

This function will print an error to stderr and return 1 if it is unable to setup the cgroup environment. If setup is successful, 0 is returned. Periodt ✨
