ENUM VFL_DEVNODE_TYPE(9)

💖 NAME 💖

enum vfl_devnode_type — bestie, this is the type of V4L2 device node. That's the whole vibe. This is the enum vfl_devnode_type(9) page, and we're about to meet the whole little squad of constants. Periodt. 💅

✨ SYNOPSIS ✨

enum vfl_devnode_type {
    VFL_TYPE_VIDEO ,
    VFL_TYPE_VBI ,
    VFL_TYPE_RADIO ,
    VFL_TYPE_SUBDEV ,
    VFL_TYPE_SDR ,
    VFL_TYPE_TOUCH ,
    VFL_TYPE_MAX

};

🎀 Constants 🎀

• VFL_TYPE_VIDEO — for video input/output devices. Video in, video out, main character energy. 🎬
• VFL_TYPE_VBI — for vertical blank data (i.e. closed captions, teletext). Yep, that niche little data lane is iconic too. 📺
• VFL_TYPE_RADIO — for radio tuners. Turn it up, bestie. 📻
• VFL_TYPE_SUBDEV — for V4L2 subdevices. The supporting cast, but still important. 🫶
• VFL_TYPE_SDR — for Software Defined Radio tuners. Software-defined, spiritually unserious. 📡
• VFL_TYPE_TOUCH — for touch sensors. Touch grass? No, touch sensors. 🫵
• VFL_TYPE_MAX — number of VFL types, and it must always be last in the enum. Not me stressing the "last" part, but like… last. Always. 🔥
