STRUCT XSDFEC_LDPC_PARAM_TABLE_SIZES(9)

💖 struct xsdfec_ldpc_param_table_sizes 💖

okay so this is a page from the Kernel API Manual, section 9, and it's about a struct — literally just a lil container that holds the sizes of the SD-FEC table entries for one individual LPDC code parameter. she's small, she's tidy, she's a struct, she ate 💅

---

✨ NAME ✨

struct xsdfec_ldpc_param_table_sizes — bestie, this is Used to store sizes of SD-FEC table entries for an individual LPDC code parameter. that's it, that's the whole job, no cap 🎀

---

🌸 SYNOPSIS 🌸

here's the whole vibe, and yes you copy it exactly, character for character, i don't make the rules:

struct xsdfec_ldpc_param_table_sizes {
    __u32 sc_size;
    __u32 la_size;
    __u32 qc_size;
 };

look at her 🥹 three __u32 fields, minding their own business.

---

🦋 Members 🦋

three members, three little icons, let's go:

• sc_size — the size of the SC table used 🫶
• la_size — the size of the LA table used ✨
• qc_size — the size of the QC table used 💫

that's the entire personality. sizes of tables. used. iconic.

ngl there are no options, no exit statuses, no environment variables and no warnings on this page — it's a struct, she's chillin', nothing dangerous here 💀

and that's the whole page, bestie! sign-off time 🎀 this one came from ./include/uapi/misc, dated October 2026, and it's the struct xsdfec_ldpc_param_table_sizes(9) page — periodt. 💜
