trace_set_clr_event(9)

💅 trace_set_clr_event(9) — Kernel API Manual, but make it cute

okay so this is trace_set_clr_event(9), straight out of the Kernel API Manual, and she's here to spill the tea on turning event recording on and off 💖

---

🎀 NAME 🎀

trace_set_clr_event — enable or disable an event, bestie. That's literally the whole job. ✨

---

🌸 SYNOPSIS 🌸

int trace_set_clr_event (const char *system , const char *event , int
       set );

---

🦋 ARGUMENTS 🦋

• system — the system name to match, and yes you can pass NULL for any system 🫶
• event — the event name to match, and NULL means all events within that system, no cap 💅
• set — 1 to enable, 0 to disable. Binary queen 👑

---

✨ DESCRIPTION ✨

This is the way for other parts of the kernel to enable or disable event recording. Like, it's giving "backstage pass to the event recorder" energy 🎟️

It returns 0 on success. If the parameters don't match any registered events, it returns -EINVAL — so yeah, if you get that, the vibe check failed 😭
