STRUCT BCH_CONTROL(9)

🌸 NAME 🌸

okay bestie, this is the Kernel API Manual page for struct bch_control(9) — aka the BCH control structure. it’s literally the struct reveal, and we’re going through every member like it’s a group-chat receipt. 💅✨

✨ SYNOPSIS ✨

       struct bch_control {
           unsigned int    m;
           unsigned int    n;
           unsigned int    t;
           unsigned int    ecc_bits;
           unsigned int    ecc_bytes;
        };

🎀 Members 🎀

• m — Galois field order. periodt.
• n — maximum codeword size in bits (= 2^m-1). no cap, that’s the whole range. 💖
• t — error correction capability in bits. iconic little number.
• ecc_bits — ecc exact size in bits, i.e. generator polynomial degree (<=m*t). highkey important. 🔥
• ecc_bytes — ecc max size (m*t bits) in bytes. slay.
