vidtv_psi_sd...date_sec_len(9)

💖 NAME 💖

okay so this is the Kernel API Manual page for vidtv_psi_sd...date_sec_len(9), and the actual function is vidtv_psi_sdt_table_update_sec_len — it recomputes and updates the SDT section length. slay 💅

✨ SYNOPSIS ✨

void vidtv_psi_sdt_table_update_sec_len (struct vidtv_psi_table_sdt *sdt
);

it’s a void function, so no return value — just the length glow-up, bestie 🫶

🎀 ARGUMENTS 🎀

• sdt — the SDT whose length is to be updated. that’s the main character here 👑

🦋 DESCRIPTION 🦋

okay so here’s the tea: this will traverse the table and accumulate the length of its components, which is then used to replace the 'section_length' field. literally adding up the pieces so the section length can be updated 💖

and if section_length > MAX_SECTION_LEN, the operation fails. that’s the limit, no cap 😭
