gsm_dlci_free(9)

💅 gsm_dlci_free

okay so real talk — this little page comes straight out of the Kernel API Manual, section 9, and it's one of those tiny-but-iconic functions that does exactly what it says on the label. no lore, no plot twists, just a DLCI getting freed. let's get into it 🎀

---

✨ NAME ✨

gsm_dlci_free — free DLCI 🦋

like. that's the whole thing. it frees the DLCI. main character energy, zero notes.

---

🌸 SYNOPSIS 🌸

void gsm_dlci_free (struct tty_port *port );

returns nothing (void, she gives nothing and takes nothing 💅) and takes exactly one thing: the port.

---

🎀 ARGUMENTS 🎀

• port — the tty port for the DLCI you wanna free. that's it, that's the whole parameter 🫶

---

💖 DESCRIPTION 💖

Free up a DLCI. periodt. no cap, that's the entire job description 🔥

okay but the one detail you cannot skip: it can sleep. literally, it is allowed to sleep 😴 — so be a thoughtful bestie and keep that in mind wherever you're calling it from.

don't sleep on the "can sleep" note (pun fully intended) — it's the only caveat on this whole page and it's there for a reason 💀
