STRUCT DVB_USB_ADAPTER(9)

💅 struct dvb_usb_adapter(9)

okay so bestie, welcome to the Kernel API Manual page for struct dvb_usb_adapter — literally the main character of DVB-over-USB setups ✨

🦋 NAME

struct dvb_usb_adapter — a DVB adapter on a USB device. that's it, that's the vibe 🎀

🌸 SYNOPSIS

struct dvb_usb_adapter {
    struct dvb_usb_device *dev;
    struct dvb_usb_adapter_properties props;
  #define DVB_USB_ADAP_STATE_INIT 0x000;
  #define DVB_USB_ADAP_STATE_DVB  0x001;
    int state;
    u8 id;
    int feedcount;
    struct dvb_adapter   dvb_adap;
    struct dmxdev        dmxdev;
    struct dvb_demux     demux;
    struct dvb_net       dvb_net;
    struct dvb_usb_fe_adapter fe_adap[MAX_NO_OF_FE_PER_ADAP];
    int active_fe;
    int num_frontends_initialized;
    void *priv;
 };

no cap, those two #defines are literally inside the struct body up there — DVB_USB_ADAP_STATE_INIT is 0x000; and DVB_USB_ADAP_STATE_DVB is 0x001;. copying exactly, periodt 💅

👑 Members

• dev — the DVB USB device pointer. your whole device-crushing situation 🫶
• props — properties. it's giving configuration energy.
• state — status. where the adapter is at, emotionally and technically ✨
• id — index of this adapter, and it starts with 0 (classic zero-indexing slay).
• feedcount — number of requested feeds (used for streaming-activation). count those feeds bestie 🔥
• dvb_adap — the device's dvb_adapter.
• dmxdev — the device's dmxdev.
• demux — the device's software demuxer.
• dvb_net — the device's dvb_net interfaces.
• fe_adap — frontend adapters.
• active_fe — active frontend. only one gets the crown at a time 👑
• num_frontends_initialized — number of initialized frontends.
• priv — private pointer. mysterious. iconic. we love a private king 💜
