scsw_ectl(9)

💅 scsw_ectl — return scsw ectl field

okay so welcome to scsw_ectl(9), straight out of the Kernel API Manual bestie, and honestly? she's a tiny little icon and we stan 🎀

---

✨ NAME ✨

scsw_ectl — return scsw ectl field

like... that's it, that's the whole job, and she does it flawlessly 💁‍♀️

---

🌸 SYNOPSIS 🌸

u32 scsw_ectl (union scsw *scsw );

yep, that's the whole signature. returns a u32, takes one pointer, no drama, no cap 💖

---

🦋 ARGUMENTS 🦋

• scsw — pointer to scsw 👑 that's your union scsw *, and yes bestie it's a pointer, so don't go handing her a bare union, she wants the address

---

💫 DESCRIPTION 💫

so what she does is: return the value of the ectl field of the specified scsw 🔥

and here's the slay part — it does not care whether it's a transport mode scsw or a command mode scsw. like, it truly does not gaf. transport mode? command mode? both get the same ectl-grabbing treatment, no vibe check required, no branching, just vibes and a return value ✨

it's giving "one job, done perfectly" energy, and I'm obsessed 🫶
