hal_exit(3hal)

✨ hal_exit — the manual page, but make it cute ✨

okay bestie, welcome to hal_exit(3hal), straight outta the HAL section of the LinuxCNC docs 💖 this is the little cleanup icon that closes the door behind you when your HAL era is over.

---

🌸 NAME 🌸

hal_exit — shut down HAL 🫶

---

🎀 SYNTAX 🎀

int hal_exit(int comp_id)

---

💅 ARGUMENTS 💅

• comp_id — the HAL component identifier you got handed back from an earlier call to hal_init. yeah, that one. keep it safe, you need it here 👑

---

🦋 DESCRIPTION 🦋

hal_exit shuts down and cleans up HAL and RTAPI. like, full glow-down, everything tidied, no crumbs left. ✨

and listen — it must be called prior to exit by any module that called hal_init. no skipping, no "i'll do it later", no leaving your HAL stuff just hanging there. if you initialized, you clean up. periodt. 💀

---

⏰ REALTIME CONSIDERATIONS ⏰

call this one only from within non-realtime or init/cleanup code. do not call it from realtime tasks. not the vibe, not allowed, do not pass go 🙈

---

🌈 RETURN VALUE 🌈

returns a HAL status code. that's it, that's the tea 🍓

---

so yeah — init with hal_init, live your HAL main character era, then hal_exit on the way out. iykyk 💜
