ASSERT_NE(9)

✨ ASSERT_NE(9) ✨

okay so bestie, welcome to the Kernel API Manual entry for ASSERT_NE(9) — yes that's the man page title, no I'm not gonna make you read a header line twice, we're folding that in like a good little intro 🎀

---

💖 NAME 💖

ASSERT_NE — and that's it. That's the whole description. The NAME line after the dash is literally empty 😭 no cap, nothing follows the hyphen. Iconic of it honestly. The real tea is all further down 👇

---

🌸 SYNOPSIS 🌸

ASSERT_NE (expected , seen );

that's the whole call, bestie, copy it exactly — note the space before the comma and the semicolon at the end, keep it character for character 💅

---

🦋 ARGUMENTS 🦋

• expected — the value you're expecting, i.e. the one your brain says it should be
• seen — the value you actually measured, i.e. what the code really handed you 👀

---

🧚 DESCRIPTION 🧚

ASSERT_NE(expected, measured) — and the vibe check is:

expected != measured

that's it. that's the whole thing. it asserts they are not equal. if expected and measured turn out to be the same, it's giving 💀, not slay. periodt. 🫶
