KUNIT_EXPECT_NOT_NULL(9)

🌸 NAME 🌸

Okay so this is the KUNIT_EXPECT_NOT_NULL page from the Kernel API Manual — manual name folded in near the top like a little name tag 🫶. Short version: it expects that @ptr is not null. Not me being obsessed with pointer existence, but here we are 💅.

✨ SYNOPSIS ✨

KUNIT_EXPECT_NOT_NULL (test , ptr );

🎀 ARGUMENTS 🎀

• test — The test context object. It’s the main-character container for the test context, no cap.
• ptr — an arbitrary pointer. Literally any pointer, bestie. 🦋

💖 DESCRIPTION 💖

So KUNIT_EXPECT_NOT_NULL sets an expectation that the value that ptr evaluates to is not null. This is semantically equivalent to KUNIT_EXPECT_PTR_NE(test, ptr, NULL) — same energy, different spelling. See KUNIT_EXPECT_TRUE for more information.

bestie note: the original says to see KUNIT_EXPECT_TRUE for more information, so that’s the next little rabbit hole if you want extra deets 🐇✨
