EXPECT_TRUE(9)

💖 EXPECT_TRUE(9) 💖

okay so bestie, we're looking at EXPECT_TRUE, a kernel API manual page from the Kernel API Manual — yes that's the manual name, it lives in section 9, and honestly? it's giving "tiny function, big harness energy" ✨

It's one of those kselftest harness macros that checks stuff for you and then keeps going instead of bailing, iykyk.

🌸 NAME 🌸

EXPECT_TRUE — literally that's it, the original page leaves the description blank, so I'm not gonna invent one for you 🫶

---

✨ SYNOPSIS ✨

EXPECT_TRUE (seen );

---

🎀 ARGUMENTS 🎀

• seen — the measured value. that's the thing you're checking, bestie 💅

---

🦋 DESCRIPTION 🦋

Okay so the whole vibe is:

EXPECT_TRUE(measured): 0 != measured

Which means: you hand it measured, and the check is that measured is not equal to 0. zero = not it. anything else = slay 💀✨
