gsm_response(9)

💖 gsm_response(9) 💖

okay so this is a page from the Kernel API Manual — yes, the Kernel API Manual, we're being fancy today — and it's all about gsm_response, bestie. it's short, it's sweet, it sends a control response. let's get into it 🫶

---

✨ SYNOPSIS ✨

void gsm_response (struct gsm_mux *gsm , int addr , int control );

that's the whole signature. returns nothing (void), takes three things. iconic, minimal, no notes 💅

---

🎀 ARGUMENTS 🎀

• gsm — our GSM mux. our mux. ours. 🥰 (it's a struct gsm_mux *)
• addr — the address for the control frame 📬
• control — the control byte, and yes it includes the PF bit — don't forget the PF bit, i'm literally begging 🙈

---

🌸 DESCRIPTION 🌸

so what does it actually do? it formats up a link level response frame and then transmits it. that's it. that's the whole job ✨

fr fr that's the entire description in the original — format it, transmit it, done. no cap, some functions are just built different (and some are just built simple) 🦋
