ENUM SDCA_ACCESS_LAYER(9)

✨ NAME ✨

okay bestie, this is the enum sdca_access_layer(9) page from the Kernel API Manual, and it is literally all about the SDCA Control access layer. That’s the whole vibe: one enum, six access-layer constants, and the spec reference to back it up. 💅

🌸 SYNOPSIS 🌸

enum sdca_access_layer {
           SDCA_ACCESS_LAYER_USER ,
           SDCA_ACCESS_LAYER_APPLICATION ,
           SDCA_ACCESS_LAYER_CLASS ,
           SDCA_ACCESS_LAYER_PLATFORM ,
           SDCA_ACCESS_LAYER_DEVICE ,
           SDCA_ACCESS_LAYER_EXTENSION

};

🎀 CONSTANTS 🎀

• SDCA_ACCESS_LAYER_USER — -- undescribed -- bestie, the manpage literally gives us nothing else here. 💀
• SDCA_ACCESS_LAYER_APPLICATION — -- undescribed --, bestie. That’s the whole note. 🙈
• SDCA_ACCESS_LAYER_CLASS — -- undescribed --, no cap. ✨
• SDCA_ACCESS_LAYER_PLATFORM — -- undescribed --, and we are just gonna sit with that. 🫶
• SDCA_ACCESS_LAYER_DEVICE — -- undescribed --, iconic minimalism honestly. 🎀
• SDCA_ACCESS_LAYER_EXTENSION — -- undescribed --, periodt. 💖

💖 DESCRIPTION 💖

Access layers as described in the SDCA specification v1.0 section 7.1.9. That’s the source of truth, iykyk — this page is not out here inventing extra lore. 🌈
