STRUCT HEADER_WRITE_ARGS(9)

✨ struct header_write_args(9) ✨

okay so this is a page straight out of the Kernel API Manual, and it's all about one lil struct, bestie — let's get into it 💅

---

💖 NAME 💖

struct header_write_args — literally the argument bundle you pass in when you want to write the common table header. that's it, that's the whole vibe 🎀

---

🦋 SYNOPSIS 🦋

struct header_write_args {
    void *dest_buf;
    u32 dest_offset;
    struct vidtv_psi_table_header *h;
    u16 pid;
    u8 *continuity_counter;
    u32 dest_buf_sz;
    u32 *crc;
 };

yes bestie, it's a struct, it's got seven fields, and every single one of them is about to be explained. no skips, no cap 🫶

---

🌸 Members 🌸

okay so here's the field-by-field breakdown, and ngl this part is the whole main character of the page ✨

• dest_buf — the buffer you're writing into. that's the canvas, the destination, the place where the bytes go 💖
• dest_offset — where in dest_buffer you start writing. not the beginning necessarily, the offset. lowkey important 😌
• h — a pointer to the header. yes, it's just called h. iconic, honestly 👑
• pid — the TS packet ID. that's u16, no funny business.
• continuity_counter — gets incremented on every new packet. it's a u8 *, so it's a pointer to that counter, bestie 🌀
• dest_buf_sz — the size of the dest_buffer. know your limits, periodt 💀
• crc — a pointer where you store the crc for this chunk. it's a u32 *, and yes it wants somewhere to live 🌟

fr fr, that's the whole struct. seven fields, zero drama, maximum usefulness 🧚
