tracepoint_probe_unregister(9)

💅 tracepoint_probe_unregister (kernel API manual, section 9) ✨

okay bestie, so this is a page from the Kernel API Manual — section 9, iykyk — and it's all about unhooking a probe from a tracepoint. literally the breakup arc of kernel tracing 🫶

---

🌸 NAME 🌸

tracepoint_probe_unregister — disconnect a probe from a tracepoint ✂️💔

---

🦋 SYNOPSIS 🦋

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

like, that's the whole signature. three args, one int coming back. no cap. ✨

---

🎀 ARGUMENTS 🎀

• tp — the tracepoint itself, a struct tracepoint *. this is the main character of the operation 👑
• probe — the probe function pointer. the one you're breaking up with 😭
• data — the tracepoint data. comes along for the ride, as it does 🙈

---

💖 DESCRIPTION 💖

okay so here's the vibe: it returns 0 if everything's ok, and an error value on error. that's it, that's the whole description, and honestly? iconic minimalism. periodt. 🔥

ngl bestie, always check that return value — 0 means slay, anything else means something went sideways and you will be looking at an error value. 💀
