vidtv_psi_eit_write_into(9)

💅 vidtv_psi_eit_write_into(9) — like, the EIT-to-MPEG-TS writer, bestie ✨

okay so this is a page from the Kernel API Manual (yes, the kernel one, the big one 👑) and it's all about vidtv_psi_eit_write_into. Buckle up, it's short but it eats 🍓

---

🌸 NAME 🌸

vidtv_psi_eit_write_into — writes the EIT as MPEG-TS packets into a buffer. that's the whole vibe, no cap 💖

---

✨ SYNOPSIS ✨

u32 vidtv_psi_eit_write_into(struct vidtv_psi_eit_write_args *args);

---

🎀 ARGUMENTS 🎀

• args — an instance of struct vidtv_psi_nit_write_args

okay so real talk, the page literally says vidtv_psi_nit_write_args here and not the eit one 😭 i'm not touching it, i'm not "fixing" it, i'm just delivering it to you exactly as it was handed to me. verbatim queen behavior 💅

---

🦋 DESCRIPTION 🦋

so what this function does is: it writes the MPEG TS packets for an EIT table into a buffer. iconic. no notes 🔥

and here's the part you actually need to remember — calling code will usually generate the EIT by calling its init function, and because of that, the calling code is the one responsible for freeing it. like, you made it, you clean it up, that's the rule 🫶😭

---

⭐ RETURN ⭐

it returns the number of bytes written into the buffer. and listen, this is the lil gotcha that trips people up: that number is NOT equal to the size of the EIT, because more space is needed for TS headers during TS encapsulation. so don't be out here assuming bytes-written == table size, you WILL be humbled 💀
