STRUCT DVB_DEMUX_FILTER(9)

✨ struct dvb_demux_filter(9) ✨

okay so bestie, this is a page from the Kernel API Manual — yes, the actual kernel manual, we're in the big leagues now — and it's all about struct dvb_demux_filter, which is literally just a little struct that describes a DVB demux section filter. that's the whole vibe. 💅

---

🌸 NAME 🌸

struct dvb_demux_filter — describes a DVB demux section filter, no cap 🎀

---

🦋 SYNOPSIS 🦋

here's the whole struct, laid bare, every single member, don't skip any:

struct dvb_demux_filter {
    struct dmx_section_filter filter;
    u8 maskandmode[DMX_MAX_FILTER_SIZE];
    u8 maskandnotmode[DMX_MAX_FILTER_SIZE];
    bool doneq;
    struct dvb_demux_filter *next;
    struct dvb_demux_feed *feed;
    int index;
    enum dvb_dmx_state state;
    enum dvb_dmx_filter_type type;
 };

---

💖 Members 💖

okay let's go member by member, group-chat style, but like… accurately:

• filter — the section filter itself, defined by struct dmx_section_filter. the main character of the struct honestly 👑
• maskandmode — logical “and” bit mask. that's it, that's the whole job 🫶
• maskandnotmode — logical “and not” bit mask. the sequel, and yes it ate 💅
• doneq — a flag that tells you when a filter is ready. it's giving little status light energy ⭐
• next — pointer to the next section filter. linked list behavior, we love a chain 🔥
• feed — a struct dvb_demux_feed pointer. just pointing at its feed bestie 🍓
• index — the index of the used demux filter. numbers, but make it iconic 🔢
• state — the state of the filter, as described by enum dvb_dmx_state. current mood: enumerated 🌈
• type — the type of the filter, as described by enum dvb_dmx_filter_type. also enumerated, also valid 💜

that's the whole page, mwah 💋 this little icon came from ./include/media, dated October 2026, and it's filed under struct dvb_demux_filter(9) — periodt. 💖✨
