💅 struct kunit_ptr_not_err_assert — Kernel API Manual ✨

okay so bestie, welcome to the <pink>Kernel API Manual</pink> 🎀 — today's hyperfixation is struct kunit_ptr_not_err_assert(9) and honestly? she's iconic. lowkey a little niche, highkey essential. let's get into it 🫶

---

🌸 NAME 🌸

struct kunit_ptr_not_err_assert — it's an expectation/assertion that a pointer is not NULL and not a -errno. that's the whole vibe. no cap 💅

---

✨ SYNOPSIS ✨

struct kunit_ptr_not_err_assert {
    struct kunit_assert assert;
    const char *text;
    const void *value;
 };

like, look at her. three fields. flawless. periodt 👑

🦋 Members 🦋

• assert — the parent of this type. she's giving main character energy but she's literally the parent, so respect the lineage fr fr 🌈
• text — a string representation of the expression that got passed to the expectation. iykyk, it's the receipts of what you actually wrote 📝
• value — the actual evaluated pointer value of the expression. the real one. the one that gets the vibe check 🔥

---

💖 Description 💖

so basically: this struct represents an expectation/assertion that a pointer is not null and does not contain a -errno. that's it, that's the whole personality ✨

(See IS_ERR_OR_NULL.) — yes bestie, go look at it, it's right there 🙈
