STRUCT PINFUNCTION(9)

struct pinfunction(9) 💅

okay so bestie, welcome to the <struct pinfunction> page from the Kernel API Manual — it’s giving “tiny struct, very important pinctrl energy,” and we’re gonna read it together. No cap. 🫶

---

🌸 NAME 🌸

struct pinfunction — literally “Description about a function.” iconic, concise, periodt. ✨

---

✨ SYNOPSIS ✨

here’s the whole struct, exact vibes, don’t touch the formatting:

       struct pinfunction {
           const char *name;
           const char * const *groups;
           size_t ngroups;
           unsigned long flags;
        };

---

🎀 Members 🎀

• name — the name of the function, bestie. that’s it, that’s the field. 💖
• groups — an array of groups for this function — like the function’s whole friend group. 🦋
• ngroups — number of groups in groups. yes, it’s the count. she keeps the friend group organized. 🎀
• flags — additional pin function flags. extra little details, lowkey essential. ⭐

---

🦋 SEE ALSO 🦋
