💖 funct(3hal) — HAL, bestie edition 💖

okay so this is a page from the HAL manual, and it's all about one lil function that goes tap tap on the shoulder of the whole system like "hey. i'm done. i'm ready. let me in." ✨

---

🌸 NAME 🌸

hal_ready — indicates that this component is ready 🫶

---

🎀 SYNTAX 🎀

hal_ready(int comp_id)

---

💅 ARGUMENTS 💅

• comp_id — a HAL component identifier. where'd it come from? from an earlier call to hal_init. like, you gotta already have your lil ID badge before you can wave it around, yk? no badge, no entry. 🙈

---

✨ DESCRIPTION ✨

hal_ready is literally the "i'm ready!!" announcement. it tells everyone that this component is ready — meaning it has already created all its pins, its parameters, and its functions. all of them. done. built. slay. 👑

and the timing? the timing is not optional, bestie, it's giving mandatory:

• in any realtime HAL component, you must call this before its rtapi_app_init exits.
• in any non-realtime component, you must call this before it enters its main loop.

lowkey this is a hard requirement, not a vibe suggestion. skip it and you're not ready, periodt. 😭

---

🌈 RETURN VALUE 🌈

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

---

🦋 SEE ALSO 🦋

nothing listed here, bestie — this page is a solo act, main character energy only. 💜

and that's the whole page!! this one came from the LinuxCNC Documentation, dated 2006-10-12, and it lives in the funct(3hal) slot of the manual. iconic since 2006, no cap. 🎀✨
