STRUCT VIDTV_PSI_NIT_WRITE_ARGS(9)

💖 NAME 💖

struct vidtv_psi_nit_write_args — the little arg bundle you hand over when you're writing a NIT section ✨ (this is from the Kernel API Manual, bestie, so like… kernel-adjacent group chat 🫶)

🌸 SYNOPSIS 🌸

okay so here's literally the whole shape of it, no cap:

struct vidtv_psi_nit_write_args {
    char *buf;
    u32 offset;
    struct vidtv_psi_table_nit *nit;
    u32 buf_sz;
    u8 *continuity_counter;
 };

🎀 Members 🎀

each one of these is a field in the struct, and honestly they're all doing main character work 💅

• buf — the destination buffer, aka where the goods go 💖
• offset — how far into that destination buffer you are, like your little bookmark 🦋
• nit — a pointer to the NIT 👑
• buf_sz — the size of the destination buffer, so nobody overruns anything (we respect boundaries here) 🌸
• continuity_counter — a pointer to the CC, and just so you know: it gets incremented on every new packet ⭐

lowkey the continuity counter thing is the icon of this whole struct. it's giving "I keep track of packets so you don't have to" 🧚

and that's the whole page, bestie 💜

this little writeup lives at ./drivers/media/test-drivers/v... and it's dated October 2026 — so yeah, shoutout to future us 🍓 and the page header/identifier situation is struct vidt...t_write_args(9), which, yeah, they really did truncate it like that 😭 slay anyway. bye bestie! 🎀
