vidtv_psi_pa...date_sec_len(9)

💖 NAME 💖

okay so hiii bestie, welcome to the Kernel API Manual page for vidtv_psi_pa...date_sec_len(9) — the actual function is vidtv_psi_pat_table_update_sec_len, and it's literally "Recompute and update the PAT section length." That's the whole assignment, and it ate. 💅

✨ SYNOPSIS ✨

void vidtv_psi_pat_table_update_sec_len (struct vidtv_psi_table_pat *pat
);

🎀 ARGUMENTS 🎀

• pat — the PAT whose length is getting updated, periodt. This is the table getting the glow-up.

💅 DESCRIPTION 💅

So the way this works is: this traverses the table and accumulates the length of its components, which is then used to replace the 'section_length' field. Like a little length audit, but make it cute.

⚠️ bestie, hear me: if section_length > MAX_SECTION_LEN, the operation fails. No cap. That's the limit, so don't let it get too big.
