STRUCT VIDTV_PSI_SDT_WRITE_ARGS(9)

🌸 struct vidtv_psi_sdt_write_args(9) — from the Kernel API Manual, bestie 💅

okay so picture this: you're deep in the kernel source, you find this little struct hanging out in the vidtv driver, and you're like "what even is this?" ✨ Well congrats, you've found the crib notes for writing an SDT table. It's basically a little bundle of args you hand off so the write can actually happen. No cap. Keep reading, we're gonna get through it together 🫶

✨ NAME ✨

struct vidtv_psi_sdt_write_args — literally the Arguments for writing a SDT table. That's her whole job. That's the assignment. 🎀

🦋 SYNOPSIS 🦋

struct vidtv_psi_sdt_write_args {
    char *buf;
    u32 offset;
    struct vidtv_psi_table_sdt *sdt;
    u32 buf_sz;
    u8 *continuity_counter;
 };

👑 Members 👑

okay let's go member by member because each one is kind of iconic in her own way 🔥

• buf — The destination buffer. This is where the good stuff lands. Think of it as the group chat and this table's the message 💌
• offset — The offset into the destination buffer. Like, where in the buffer we're starting from. Gotta respect the placement, y'know? not me just dropping bytes at position zero 🙈
• sdt — A pointer to the SDT. Yes, THE SDT. Our main character. 🌟
• buf_sz — The size of the destination buffer. You gotta tell it how big the buffer is, bestie, otherwise how's it supposed to know where the edges are 😭
• continuity_counter — A pointer to the CC. Incremented on every new packet. She's keeping count, she's keeping track, she's literally never missing a beat 💅
