KUNIT_CASE_PARAM(9)

💖 NAME 💖

okay so welcome to KUNIT_CASE_PARAM(9) from the Kernel API Manual ✨ bestie, this one is literally a helper for creation a parameterized &struct kunit_case — yes, that's the official wording, and we're keeping it 💅

---

✨ SYNOPSIS ✨

KUNIT_CASE_PARAM (test_name , gen_params );

---

🎀 ARGUMENTS 🎀

• test_name — a reference to a test case function.
• gen_params — a reference to a parameter generator function.

---

🦋 DESCRIPTION 🦋

The generator function:

const void* gen_params(const void *prev, char *desc)

is used to lazily generate a series of arbitrarily typed values that fit into a void*. The argument prev is the previously returned value, which should be used to derive the next value; prev is set to NULL on the initial generator call. When no more values are available, the generator must return NULL. Optionally write a string into desc (size of KUNIT_PARAM_DESC_SIZE) describing the parameter. 💖
