idr_init_base(9)

🎀 NAME 🎀

idr_init_base — ok so this one initialises an IDR, bestie, that's literally the whole vibe 💅

---

✨ SYNOPSIS ✨

void idr_init_base (struct idr *idr , int base );

---

🦋 ARGUMENTS 🦋

• idr — your IDR handle 🫶 like, the actual thing you're setting up.
• base — the base value for the IDR ⭐ this is the starting number, no cap.

---

🌸 DESCRIPTION 🌸

So this is the ✨variation✨ of idr_init — and the one thing that makes it different (main character energy fr fr) is that it creates an IDR which will allocate IDs starting at base 🔥

That's it. That's the whole flex. Starting point = base. Iconic, lowkey.
