💾 stack_trace_save(9) — Kernel API Manual ✨

okay so bestie, this is stack_trace_save(9) from the Kernel API Manual, and it is literally here to save a stack trace into a storage array. That’s the whole vibe. 💖

🌸 NAME 🌸

stack_trace_save — save a stack trace into a storage array. no cap, that’s the job. 🫶

---

✨ SYNOPSIS ✨

       unsigned int stack_trace_save (unsigned long *store , unsigned int size
       , unsigned int skipnr );

---

🎀 ARGUMENTS 🎀

• store — pointer to the storage array. this is where the trace goes, bestie 💅
• size — size of the storage array. it’s giving “how much room do we have” energy.
• skipnr — number of entries to skip at the start of the stack trace. yes, literally skip that many from the beginning. periodt. ✨

---

🔥 RETURN 🔥

it returns the number of trace entries stored. that’s the count, and it’s iconic. 👑
