scsw_cmd_is_valid_cstat(9)

🎀 scsw_cmd_is_valid_cstat(9) 🎀

okay bestie, welcome to the Kernel API Manual — this one is short, cute, and very “does this field pass the vibe check?” energy. no cap, it’s a tiny validity checker and it ate. 💅

---

✨ NAME ✨

scsw_cmd_is_valid_cstat — check cstat field validity

---

🌸 SYNOPSIS 🌸

int scsw_cmd_is_valid_cstat (union scsw *scsw );

---

🫶 ARGUMENTS 🫶

• scsw — pointer to scsw

---

🦋 DESCRIPTION 🦋

so basically: return non-zero if the cstat field of the specified command mode scsw is valid, and zero otherwise. that’s the whole plot. iconic, honestly. ✨
