ASSERT_LE(9)

💅 ASSERT_LE(9) 💅

ok so this is a page from the Kernel API Manual, bestie — section 9, the kernel dev corner. sit down, grab a strawberry 🍓, we're learning about a macro that checks one number is less than or equal to another. yes that's it. no cap.

---

✨ SYNOPSIS ✨

ASSERT_LE (expected , seen );

like, that's the whole call. two things go in, vibes come out 🤭

---

🎀 ARGUMENTS 🎀

• expected — the expected value, aka the number you think it should be. your main character number 👑
• seen — the measured value, aka the number reality actually handed you. the vibe check result 🌸

---

🦋 DESCRIPTION 🦋

ASSERT_LE(expected, measured): expected <= measured

basically: the expected value has to be less than or equal to the measured one. if it is, slay, we move on ✨ if it isn't — the assertion fails, and it's giving "not me getting caught lacking" 😭💀

literally <=. that's the whole thing. ASSERT_LE is the "less than or equal" girlie of the ASSERT family. periodt 🫶

ngl, the argument is named seen in the signature but measured in the description — that's just how the docs wrote it, i'm not changing a single character of it 💖
