cs_dsp_get_ctl(9)

🌸 cs_dsp_get_ctl(9) 🌸

okay so bestie, welcome to the Kernel API Manual, section 9, and this page is all about cs_dsp_get_ctl(9). it’s giving “find the right control” energy, and honestly? iconic. 💅

---

✨ NAME ✨

cs_dsp_get_ctl — Finds a matching coefficient control. no cap. 🎀

---

🦋 SYNOPSIS 🦋

the whole vibe is this call right here:

       struct cs_dsp_coeff_ctl * cs_dsp_get_ctl (struct cs_dsp *dsp , const
       char *name , int type , unsigned int alg );

---

💖 ARGUMENTS 💖

• dsp — pointer to DSP structure. literally the main character here. 🫶
• name — pointer to string to match with a control's subname. yes, subname — keep that energy. ✨
• type — the algorithm type to match. 🌈
• alg — the algorithm id to match. ⭐

---

🎀 DESCRIPTION 🎀

Find cs_dsp_coeff_ctl with input name as its subname. that’s the whole quest, bestie. go find your matching control. 🔥

---

⭐ RETURN ⭐

pointer to the control on success, NULL if not found. so like… found it = slay, not found = NULL. periodt. 💀
