ENUM PIXEL_READ_DIRECTION(9)

🦋 enum pixel_read_direction(9) 🦋

okay so bestie, welcome to the page for enum pixel_read_direction(9) from the Kernel API Manual — it’s giving very niche kernel lore, and we’re here for it ✨

---

💖 NAME 💖

enum pixel_read_direction — Enum used internally by VKMS to represent a reading direction in a plane. slay, that’s literally the whole name section 🫶

---

🎀 SYNOPSIS 🎀

the whole enum is literally this exact thing, no cap:

enum pixel_read_direction {
    READ_BOTTOM_TO_TOP ,
    READ_TOP_TO_BOTTOM ,
    READ_RIGHT_TO_LEFT ,
    READ_LEFT_TO_RIGHT

};

---

🌸 Constants 🌸

these are the four constants, and the manpage leaves all of them as -- undescribed --, so no invented extra lore from me 😭

• READ_BOTTOM_TO_TOP — -- undescribed --
• READ_TOP_TO_BOTTOM — -- undescribed --
• READ_RIGHT_TO_LEFT — -- undescribed --
• READ_LEFT_TO_RIGHT — -- undescribed --
