STRUCT KUNIT_BINARY_PTR_ASSERT(9)

💅 struct kunit_binary_ptr_assert(9)

okay so this is from the Kernel API Manual and it's genuinely one of those little structs that makes kernel testing not a total nightmare, so let's get into it 🫶

✨ NAME ✨

struct kunit_binary_ptr_assert — it's the expectation/assertion type that compares two pointer values, like when you write KUNIT_EXPECT_PTR_EQ(test, foo, bar) 💖

🌸 SYNOPSIS 🌸

struct kunit_binary_ptr_assert {
    struct kunit_assert assert;
    const struct kunit_binary_assert_text *text;
    const void *left_value;
    const void *right_value;
 };

🎀 Members 🎀

• assert — the parent of this type, it's giving "I inherited this, respectfully" 🌈
• text — holds the textual representations of the operands and the op (e.g. "==") ✨
• left_value — the actual evaluated value of the expression in the left slot 👈
• right_value — the actual evaluated value of the expression in the right slot 👉

🦋 Description 🦋

so this struct represents an expectation/assertion that compares two pointer values, no cap 💀

for example, if you wanna expect that foo and bar point to the same thing, you can use the expectation KUNIT_EXPECT_PTR_EQ(test, foo, bar); — literally that simple, slay 🔥
