ASSERT_STREQ(9)

💜 ASSERT_STREQ — the kernel API manual, bestie edition ✨

okay so real talk, this is a page from the Kernel API Manual, section 9, and it's a short one — but every crumb of it is here, promise 🫶

---

🌸 NAME 🌸

ASSERT_STREQ — and that's... literally it, bestie 😭 the original has the dash and then nothing after it. No description, no tagline, the NAME line just trails off like a text message you forgot to finish. So we move on 💅

---

✨ SYNOPSIS ✨

ASSERT_STREQ (expected , seen );

that's the whole vibe check — you call it, you give it two things, and it does its little check 🎀

---

🦋 ARGUMENTS 🦋

• expected — the expected value 👑 like, this is the one you're manifesting
• seen — the measured value 🌸 aka the one reality actually handed you

---

💖 DESCRIPTION 💖

ASSERT_STREQ(expected, measured): !strcmp(expected, measured)

so basically 👏 it's !strcmp on the two strings — you pass in what you wanted (expected) and what you got (measured), and it does the comparing for you. no cap, that's the entire bit 🧚

ngl the signature here says expected , seen up top and then the description calls the second one measured — that's just how the original rolls, so don't come for me, I'm reporting it verbatim 🙈
