insn_init(9)

okay so bestie, welcome to insn_init(9) from the Kernel API Manual 💖 this one is short and sweet: it's the setup step for a struct insn, and then the rest of the insn_* crew can do their thing. ✨

✨ NAME ✨

insn_init — initialize struct insn 🎀

🛠️ SYNOPSIS 🛠️

void insn_init (struct insn *insn , const void *kaddr , int buf_len ,
       int x86_64 );

🌸 ARGUMENTS 🌸

• insn — the struct insn to be initialized, bestie. This is literally its main-character setup moment. 💅
• kaddr — the address (in kernel memory) of the instruction, or a copy thereof. Iconic little pointer energy. ✨
• buf_len — length of the insn buffer at kaddr. Keep an eye on this one 👀
• x86_64 — !0 for a 64-bit kernel or 64-bit app. That's the whole vibe check. 🫶
