ASSERT_LT(9)

💖 ASSERT_LT(9) 💖

okay so bestie, this is a section 9 kernel API manual page, and it's literally the shortest glow-up ever — but we're gonna make it iconic anyway. It's called ASSERT_LT, and yes, it's about to be your new fave comparison macro. 🎀

---

✨ SYNOPSIS ✨

ASSERT_LT (expected , seen );

like, that's it. that's the whole vibe. 🦋

---

🌸 ARGUMENTS 🌸

• expected — the expected value, aka the number you were manifesting ✨
• seen — the measured value, aka the number that actually showed up to the party 🙈

---

💅 DESCRIPTION 💅

ASSERT_LT(expected, measured): expected < measured

no cap, that's the entire description. it checks that expected is less than measured, periodt. the way this macro does exactly one thing and does it flawlessly — main character energy fr fr. 🔥
