trace_instance_init(9)

trace_instance_init(9) 💅✨

okay so welcome to the Kernel API Manual page for trace_instance_init(9) — and bestie, this one is giving “tiny function, big responsibilities.” 🎀

---

🌸 NAME 🌸

trace_instance_init — create a trace instance. periodt. 💖

---

✨ SYNOPSIS ✨

int trace_instance_init (struct trace_instance *trace , char *name );

---

🎀 ARGUMENTS 🎀

• trace — the page literally says “undescribed”. no cap. it’s giving mysterious main-character struct-pointer energy. 🙈
• name — also “undescribed”. the manual is gatekeeping, not me, i promise. 😭

---

🦋 DESCRIPTION 🦋

It is more than the tracefs instance, because it contains other things required for the tracing, such as the local events and a seq file. 💅

Heads up, bestie: the trace instance is returned disabled. this is intentional! it allows the tool to apply some other configs, like setting priority to the kernel threads, before starting generating trace entries. 👑

Returns 0 on success, non-zero otherwise. slay. ✅
