STRUCT MEDIA_PAD(9)

🌈 struct media_pad(9) — Kernel API Manual 🌈

🌸 NAME 🌸

struct media_pad — a media pad graph object. That's the whole vibe, bestie. ✨

🦋 SYNOPSIS 🦋

struct media_pad {
    struct media_gobj graph_obj;
    struct media_entity *entity;
    u16 index;
    u16 num_links;
    enum media_pad_signal_type sig_type;
    unsigned long flags;
    struct media_pipeline *pipe;
};

💖 Members 💖

Okay, meet the cast of this struct — every field matters, no skipping. 🫶

• graph_obj — the embedded structure holding the media object's common data. It's giving "shared foundation" energy. ✨
• entity — the entity this pad belongs to. Your fave's home base. 💅
• index — pad index in the entity pads array, numbered from 0 to n. Literally the seat number, bestie. 🎀
• num_links — number of links connected to this pad. The link count, periodt. ✨
• sig_type — type of the signal inside a media pad. Signal type, slay. 💜
• flags — pad flags, as defined in :ref:include/uapi/linux/media.h <media_header> (seek for MEDIA_PAD_FL_*). Important: look for that pattern, bestie. 👑
• pipe — pipeline this pad belongs to. Use media_entity_pipeline to access this field. That's the access path, no cap. 🫶
