FUNCTION::RETURNVAL(3stap)

✨ NAME ✨

function::returnval — the possible return value of a probed function 💅 (yes bestie, possible, we'll get to that)

---

🦋 SYNOPSIS 🦋

returnval:long()

---

🎀 ARGUMENTS 🎀

None. Zero. Nada. She takes no arguments, she's low-maintenance like that 🫶

---

💖 DESCRIPTION 💖

Okay so here's the tea: returnval hands you back the value sitting in the register where function values are typically returned. That's it, that's the whole vibe.

You'd reach for this when you're in a probe where $return just isn't available to you — she said "not today" and left the chat 😭. Very common energy in dwarfless probes, where that's basically the only move you've got.

🚨 BUT. Listen. This is only a guess of the actual return value, and it can be totally wrong. Not "kinda off", not "close enough" — totally wrong. It's giving "trust me bro" energy. Use it knowing that, bestie 💀
