FUNCTION::ULONG_ARG(3stap)

💖 NAME 💖

function::ulong_arg — bestie, this one hands you a function argument back as an unsigned long. That's it. That's the whole job. And it eats. ✨

---

🌸 SYNOPSIS 🌸

ulong_arg:long(n:long)

Look at her. Short, sweet, slays. 🎀

---

🦋 ARGUMENTS 🦋

• n — the index of the argument you want back. Like, which one. The position. You point, she delivers. 💅

---

✨ DESCRIPTION ✨

So the vibe is: give her n, and she returns the value of argument n as an unsigned long. Simple. Iconic. No notes.

Now here's the little lore drop you need, bestie: on architectures where a long is 32 bits, that value gets zero-extended to 64 bits. So it's not just sitting there being 32-bit and sad — no, it's getting stretched out to a full 64, with zeros padding the top. Glow up, honestly. 🦋✨

Heads up: if your arch has a 64-bit long already, there's nothing to extend — she just gives it to you as-is. The zero-extension is specifically an on-architectures-where-a-long-is-32-bits situation. iykyk. 💜

Okay and real quick, the boring-but-important receipts: this whole thing lives in the SystemTap Tapset Reference, manual section 3stap, under the Context Functions chapter, and this particular printing is dated September 2026. Periodt. 💖✨🎀🦋🌸💅👑
