STRUCT DMX_SCT_FILTER_PARAMS(9)

💅 struct dmx_sct_filter_params — Kernel API Manual energy, bestie 🎀

okay so this is the page for struct dmx_sct_filter_params(9) — say that three times fast, I dare you 😭 it lives in the Kernel API Manual and it's genuinely the blueprint for how you tell the kernel "hey bestie, filter this section for me".

---

✨ NAME ✨

struct dmx_sct_filter_params — literally Specifies a section filter. that's the whole vibe. 🦋

---

🌸 SYNOPSIS 🌸

struct dmx_sct_filter_params {
    __u16 pid;
    struct dmx_filter filter;
    __u32 timeout;
    __u32 flags;
  #define DMX_CHECK_CRC       1;
  #define DMX_ONESHOT         2;
  #define DMX_IMMEDIATE_START 4;
 };

look at her. she's giving structured, she's giving organized, she's giving "I know exactly what I want and I'm not sorry". periodt 💅

• pid — the PID to be filtered. this is the one you're stalking (affectionately). 👀
• filter — the section header filter, exactly as defined by struct dmx_filter. yep, she's got a whole other struct inside her. nested queen behavior. 👑
• timeout — maximum time to filter, in milliseconds. the deadline. the "you have until this moment, don't test me" energy. ⏰
• flags — extra flags for the section filter. the little toggles that change everything. ✨

💖 Description 💖

She Carries the configuration for a MPEG-TS section filter. that's her whole job and she does it flawlessly, no notes. 🧚

The flags can be:

• DMX_CHECK_CRC — only deliver sections where the CRC check succeeded. no junk allowed, we check the vibes and the bytes. 🔥
• DMX_ONESHOT — disable the section filter after one section has been delivered. one and done, she's out, she said what she said. 💀
• DMX_IMMEDIATE_START — Start filter immediately without requiring a DMX_START. she doesn't wait for permission, she's the main character. ⭐

lowkey important: DMX_IMMEDIATE_START is literally the "no DMX_START needed" flag, so don't go calling it and then wondering why nothing happens — that's the whole point, bestie 🫶
