✨ register_fprobe_syms(9) ✨

Kernel API Manual, bestie — okay so this is the page for register_fprobe_syms, and it's giving “register your fprobe by symbols” energy.

---

🌸 NAME 🌸

register_fprobe_syms — Register fprobe to ftrace by symbols. Literally that. No cap.

---

🦋 SYNOPSIS 🦋

Here's the exact signature, keep it safe:

int register_fprobe_syms (struct fprobe *fp , const char **syms , int num );

---

🎀 ARGUMENTS 🎀

• fp — a fprobe data structure that's getting registered. That's the main character here.
• syms — an array of target symbols. Yep, the whole squad of symbols.
• num — the number of entries in syms. So it knows how many besties are in the array.

---

💅 DESCRIPTION 💅

Register fp to the symbols given by the syms array. This is highkey useful if you're sure the symbols exist in the kernel — like, you already know they're there, iykyk.

Return 0 if fp is registered successfully, and -errno if not. That's the whole return vibe.

Vibe check: this one is for when you're confident the target symbols are present in the kernel. Don't come for me — that's what the page says. 🫶
