STRUCT MUX_ADBH(9)

✨ NAME ✨

struct mux_adbh — the blueprint for the Aggregated Data Block Header, bestie 💅 this is the lil' label that sits on top of a whole pile of data blocks and tells everyone what's inside.

🌸 SYNOPSIS 🌸

struct mux_adbh {
    __le32 signature;
    __le16 reserved;
    __le16 sequence_nr;
    __le32 block_length;
    __le32 first_table_index;
};

okay so that's literally the whole thing, and every field is doing its own little job, no cap 🫶

🎀 Members 🎀

• signature — the signature of the Aggregated Data Block Header. it's giving ✨identity✨, the "hey bestie it's me" of the struct 🔥
• reserved — reserved bytes. set it to zero, periodt. don't be quirky with this one 🙈
• sequence_nr — the block sequence number. it's the little counter that keeps track of where this block sits in the lineup 🦋
• block_length — the length, in bytes, of the Aggregated Data Block. so like… how many bytes is the whole block, that's the vibe check 💜
• first_table_index — the index, in bytes, pointing to the first Datagram Table in the buffer. it's the map pin 📍 that says "the tables start over here bestie" 👑
