rtapi_exit(3rtapi)

✨ rtapi_exit ✨

okay so bestie, welcome to the RTAPI manual — this one's rtapi_exit(3rtapi), and it's literally the "bye bye" button for RTAPI. short page, but important, so stay with me 🫶

🌸 NAME 🌸

rtapi_exit — Shut down RTAPI

---

🎀 SYNTAX 🎀

int rtapi_exit(int module_id)

💅 ARGUMENTS 💅

• module_id — the rtapi module identifier that an earlier call to rtapi_init handed you back. yes, the same one. don't make one up, she'll know 🙈

---

🦋 DESCRIPTION 🦋

rtapi_exit shuts down and cleans up the RTAPI. that's the whole vibe: teardown, tidy up, leave the place spotless ✨

and it is not optional — it must be called prior to exit by any module that called rtapi_init. like, if you opened it, you close it. no ghost modules haunting the place 👑

---

🌈 REALTIME CONSIDERATIONS 🌈

call this only from within non-realtime or realtime init/cleanup code. do NOT call it from realtime tasks. like, not the move, bestie 💀

---

⭐ RETURN VALUE ⭐

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

---

real talk: if you called rtapi_init, you owe RTAPI an rtapi_exit. periodt 💖

mwah, that's the page 💜 this lil gem comes from the LinuxCNC Documentation, dated 2006-10-12 — vintage but still iconic, no cap. take care of your modules and they'll take care of you 🧚✨
