💖 pccard_read_tuple(9) 💖

ok so welcome to the group chat, bestie ✨ this one lives in section 9 of the Kernel API Manual and it's literally called pccard_read_tuple — say that three times fast, i dare you 🫶

---

🌸 NAME 🌸

pccard_read_tuple — internal CIS tuple access 💅

like, internal. it's giving backstage-pass energy, not front-door energy, iykyk 🎀

---

✨ SYNOPSIS ✨

int pccard_read_tuple (struct pcmcia_socket *s , unsigned int function ,
cisdata_t code , void *parse );

four arguments, one int coming back atcha, no cap 🔥

---

🦋 ARGUMENTS 🦋

• s — the struct pcmcia_socket where the card is inserted 💳 like, which slot, which socket, where is the actual card, that one
• function — the device function we loop for 🔁 (an unsigned int, be normal about it)
• code — which CIS code shall we look for? 👀 yes it's phrased as a question, yes we're answering it, the type is cisdata_t
• parse — buffer where the tuple shall be parsed, or NULL if you don't want a parse 🙈 that's it, that's the opt-out, just pass NULL and vibe

---

🌈 DESCRIPTION 🌈

ok so pccard_read_tuple reads out one tuple and then attempts to parse it 🧚 one (1) tuple. singular. main character energy, no ensemble cast 💜
