ENUM NVEC_MSG_CATEGORY(9)

📦 version 7.3.1, in nixpkgs unstable

🌸 enum nvec_msg_category(9) — the kernel API manual, bestie edition 🌸

okay so real talk, this is enum nvec_msg_category from section 9 of the Kernel API Manual, and it's honestly so simple it's iconic. it's just a little enum that tells nvec_msg_alloc() which direction a message is going. that's it. that's the whole vibe. 🎀

✨ NAME ✨

enum nvec_msg_category — Message categories for nvec_msg_alloc()

like, the literal category system for the messages. the "are you coming or going" of the nvec world. 💅

🦋 SYNOPSIS 🦋

enum nvec_msg_category {
    NVEC_MSG_RX ,
    NVEC_MSG_TX

};

yes bestie, that's the entire thing, two members, no drama, no cap. 🫶

🌈 Constants 🌈

  • NVEC_MSG_RX — The message is an incoming message (from EC) 📥
  • NVEC_MSG_TX — The message is an outgoing message (to EC) 📤

so RX = it's coming at you from the EC, TX = you're sending it to the EC. reception vs. transmission. reading vs. writing. iykyk. it's giving very main character energy for such a tiny enum honestly. 🔥

the way this list just keeps going 😭 but like, respectfully, they're all doing their thing and we love that for them.

ngl this page is short but it ate. go read nvec_msg_alloc(9) next if you wanna see where these categories actually get used, bestie. 💖
