ENUM FE_HIERARCHY(9)

✨ enum fe_hierarchy(9) ✨

okay so this is a page from the Kernel API Manual, bestie, and it's all about enum fe_hierarchy — literally the hierarchy enum, that's the whole vibe 🎀

---

🌸 NAME 🌸

enum fe_hierarchy — Hierarchy. yes that's it. that's the name. short and iconic 💅

---

🦋 SYNOPSIS 🦋

enum fe_hierarchy {
    HIERARCHY_NONE ,
    HIERARCHY_1 ,
    HIERARCHY_2 ,
    HIERARCHY_4 ,
    HIERARCHY_AUTO

};

like, that's the whole thing. five constants, no notes ✨

---

🎀 Constants 🎀

• HIERARCHY_NONE — No hierarchy. none. zero. the void. 🙈
• HIERARCHY_1 — Hierarchy 1
• HIERARCHY_2 — Hierarchy 2
• HIERARCHY_4 — Hierarchy 4
• HIERARCHY_AUTO — Autodetect hierarchy (if supported) — note the if supported part, because plot twist 👀

---

💖 Description 💖

okay so real talk: please note that not all hierarchy types are supported by a given standard. like, don't just assume every standard's gonna serve you every hierarchy level, because it won't, and that's just how it is 🫶

one little reminder before you go: not every hierarchy type is supported by every standard — check before you assume, iykyk 💀

that's the page!! 🧚 from ./include/uapi/linux/dvb, dated October 2026, and this whole thing was enum fe_hierarchy(9) — thanks for coming to my ted talk, mwah 💜🌸
