DEFINE_IDTENTRY_ERRORCODE(9)

💖 DEFINE_IDTENTRY_ERRORCODE(9) 💖

okay bestie, welcome to the Kernel API Manual — this one's a macro from the x86 IDT entry-point cinematic universe and honestly it's giving ✨niche but essential✨

---

🌸 NAME 🌸

DEFINE_IDTENTRY_ERRORCODE — literally emits code for simple IDT entry points, the kind where the error code gets pushed by hardware 🫶

---

✨ SYNOPSIS ✨

DEFINE_IDTENTRY_ERRORCODE (func );

---

🎀 ARGUMENTS 🎀

• func — the function name of the entry point, i.e. what you're gonna call this bad boy 💅

---

🦋 DESCRIPTION 🦋

no cap, it's the same as DEFINE_IDTENTRY, except it has an extra error_code argument. that's it. that's the whole vibe. the hardware already pushed the error code for you, so this macro's whole personality is making room for it 😌
