okay bestie, welcome to the Kernel API Manual — yes, that's the manual name, we're in the kernel section, section 9, and this is THE page for tracepoint_probe_register. buckle up 🎀

✨ NAME ✨

tracepoint_probe_register — Connect a probe to a tracepoint 🫶

like, literally hooking your little probe handler onto a tracepoint. match made in heaven, no cap.

---

🌸 SYNOPSIS 🌸

int tracepoint_probe_register (struct tracepoint *tp , void *probe ,
void *data );

look at her go 😭 iconic signature fr fr.

---

🦋 ARGUMENTS 🦋

• tp — tracepoint. the main character of this whole situation 👑
• probe — probe handler. this is the function doing the actual work 💪
• data — tracepoint data. the little sidekick that gets passed along 🍓

---

💖 DESCRIPTION 💖

Returns 0 if ok, error value on error. that's it, that's the vibe ✨

---

⭐ NOTE ⭐

⚠️ okay listen up, this part is important, do NOT skip it:

if tp is within a module, the caller is responsible for unregistering the probe before the module is gone. yes, you, bestie — it's on you 🙈

This can be performed either with a tracepoint module going notifier, or from within module exit functions. pick your fighter 💅
