cs_dsp_creat...ck_xm_header(9)

🎀 cs_dsp_creat...ck_xm_header(9) 🎀

okay bestie so this is a page from the Kernel API Manual, and yes the title is doing that truncated thing (cs_dsp_creat...ck_xm_header(9)) — it's just cs_dsp_create_mock_xm_header, the name got squished by the man page formatter. Iconic of it, honestly. 💅

---

✨ NAME ✨

cs_dsp_create_mock_xm_header — literally just makes a dummy XM header. That's the whole vibe. 🫶

---

🌸 SYNOPSIS 🌸

struct cs_dsp_mock_xm_header * cs_dsp_create_mock_xm_header (struct
cs_dsp_test *priv , const struct cs_dsp_mock_alg_def *algs , size_t
num_algs );

---

🦋 ARGUMENTS 🦋

• priv — a pointer to struct cs_dsp_test. Just the test context, your lil' home base. 🏠
• algs — pointer to an array of struct cs_dsp_mock_alg_def that lists which dummy algorithm entries go into the XM header. iykyk, it's the guest list 💌
• num_algs — the number of entries in the algs array. gotta tell it how many guests are actually showing up 🔥

---

⭐ RETURN ⭐

It hands you back a pointer to the freshly created struct cs_dsp_mock_xm_header. no cap, that's it. 🎁

ngl that's a whole lot of cs_dsp_mock_* friends but they're all serving in their own way 🧚
