STRUCT SMEM_PTABLE(9)

💅 struct smem_ptable(9) — Kernel API Manual, bestie edition

okay so this is a page from the Kernel API Manual and it's all about struct smem_ptable, which lowkey sounds scary but is literally just the partition table for the private partitions. that's the whole vibe. 🎀

✨ NAME ✨

struct smem_ptable — partition table for the private partitions

like, it's the little index card that says "here's where all our private partitions live." iconic behavior honestly. 🗂️

---

✨ SYNOPSIS ✨

struct smem_ptable {
    u8 magic[4];
    __le32 version;
    __le32 num_entries;
    __le32 reserved[5];
    struct smem_ptable_entry entry[];
};

look at her. five fields and a flexible array member. main character energy fr fr. 💖

✨ Members ✨

• magic — the magic number, and no cap it must be SMEM_PTABLE_MAGIC. it's giving secret handshake. if it's not that, it's not it. 🔮
• version — the version of the partition table. yes bestie, we're versioning things, we're being responsible. 💅
• num_entries — how many partitions are in the table. the count, the receipts, the number. 🔢
• reserved — reserved entries, like for now. they're just sitting there being mysterious and unbothered. 🙈
• entry — the list of smem_ptable_entry for the num_entries partitions. one per partition, slay. ✨
