vidtv_psi_nit_write_into(9)

💅 vidtv_psi_nit_write_into

okay bestie, welcome to the vidtv_psi_nit_write_into page from the Kernel API Manual — yes the whole manual, we're being fancy today ✨

---

🌸 NAME 🌸

vidtv_psi_nit_write_into — literally writes a NIT out as MPEG-TS packets into a buffer. That's the whole job. She's focused, she's iconic, she does one thing 💖

---

✨ SYNOPSIS ✨

u32 vidtv_psi_nit_write_into(struct vidtv_psi_nit_write_args *args);

---

🎀 ARGUMENTS 🎀

• args — an instance of struct vidtv_psi_nit_write_args. That's your little bundle of everything the function needs, no cap 🫶

---

🦋 DESCRIPTION 🦋

So basically, this function writes the MPEG TS packets for a NIT table into a buffer. NIT, packets, buffer — done 💅

And here's the part you actually need to remember: calling code will usually generate the NIT via a call to its init function, and therefore it is the caller's responsibility to free it. Yes bestie, you made it, you clean it up. No leaving your NIT lying around like last time 😭

---

🔥 RETURN 🔥

Returns the number of bytes written into the buffer, as a u32.

Heads up, this is NOT equal to the size of the NIT — because more space is needed for TS headers during TS encapsulation. So don't come for her when the numbers don't match, the headers are eating the extra bytes, periodt 💀
