pt_range_to_end_index(9)

💅 pt_range_to_end_index(9) — like, the Kernel API Manual page, bestie ✨

Okay so grab a snack 🍓 because we're diving into pt_range_to_end_index(9) from the Kernel API Manual, and honestly? She's a little icon. Short page, main character energy, zero filler. Let's go 🫶

🌸 NAME 🌸

pt_range_to_end_index — ending index iteration. That's it, that's the vibe: it's the ending index, and it's about iterating. Periodt 💅

---

✨ SYNOPSIS ✨

unsigned int pt_range_to_end_index (const struct pt_state *pts );

Yep, that's the whole signature. Copy it exactly, don't get cute with it 🔥

---

🎀 ARGUMENTS 🎀

• pts — the Iteration State. She's a const struct pt_state *, so hands off, we're just looking 👀

---

⭐ RETURN ⭐

It gives you back the last index for the iteration in pts. Like the final stop on the group chat road trip, no cap 🚗💨 The return type is unsigned int, and that is not a drill.
