STRUCT MUX_ACBH(9)

💅 struct mux_acbh(9) — like, the Kernel API Manual, bestie ✨

okay so picture this: you're deep in the mux_acbh part of the Kernel API Manual and you're like "what even is this struct?" — don't worry, I got you 🫶

🌸 NAME 🌸

struct mux_acbh — the Structure of the Aggregated Command Block Header. that's it, that's the vibe 💖

✨ SYNOPSIS ✨

struct mux_acbh {
    __le32 signature;
    __le16 reserved;
    __le16 sequence_nr;
    __le32 block_length;
    __le32 first_cmd_index;
 };

like, look at her. five fields, all business, no cap 👑

🎀 Members 🎀

girl, let's go through them one by one, main character by main character:

• signature — the Signature of the Aggregated Command Block Header. it's giving "hello, it's me" energy 🌈
• reserved — Reserved bytes. set it to zero, bestie, no funny business 🙈
• sequence_nr — the Block sequence number. keeping track of where we are in the lineup, periodt 💅
• block_length — the Length (in bytes) of the Aggregated Command Block. the way this literally just tells you how big the block is 😭
• first_cmd_index — the Index (in bytes) to the first command in the buffer. your little map to where the first command is chilling 🦋
