sdca_regmap_volatile(9)

✨ sdca_regmap_volatile(9) ✨

Ok bestie, so this one lives in the kernel API manual — section 9, the kernel-internals girlies 💅 — and it's literally the vibe-check function of the SDCA regmap family. Its whole personality? Telling you whether a given SDCA Control is volatile. That's it, that's the function 🎀

---

🌸 NAME 🌸

sdca_regmap_volatile — returns whether a given SDCA Control is volatile ✨

---

🦋 SYNOPSIS 🦋

bool sdca_regmap_volatile (struct sdca_function_data *function ,
unsigned int reg );

No cap, that's the exact signature — bool in, bool out, two args, periodt.

---

💖 ARGUMENTS 💖

• function — Pointer to the Function information. iykyk, it's the struct with all the deets about the Function you're poking at 🫶
• reg — Register address/Control to be processed. The one getting the vibe check 🔥

---

👑 RETURN 👑

Returns true if the register is volatile. Fr fr, that's the whole answer — no sneaky false lore, no other exit codes, just a clean little boolean 💀
