pt_next_entry(9)

🎀 NAME 🎀

Okay bestie, welcome to pt_next_entry(9) — yes, that's the title, and this whole page lives in the Kernel API Manual. The function is literally here to advance pts to the next entry. Slay.

✨ SYNOPSIS ✨

void pt_next_entry (struct pt_state *pts );

🦋 ARGUMENTS 🦋

• pts — the iteration state. She's the main character here, and updating her is the whole point.

💅 DESCRIPTION 💅

So what's the vibe? pt_next_entry updates pts so it goes to the next index at this level. That's it, that's the move.

But bestie, listen: if pts is pointing at a contiguous entry, the index may advance by more than one. Not me warning you that this is not always a cute little +1 😭. Do not assume one-step-only, iykyk.
