💖 enum nvme_id_ctrl_cntrltype 💖

okay bestie so we're in the libnvme(2) API manual, and today's main character is literally just a little enum. yes, an enum. and she's iconic for it. 🫶

✨ NAME ✨

enum nvme_id_ctrl_cntrltype — Controller types

like. that's it. that's the whole vibe. it tells you what kind of controller you're looking at. 💅

🌸 SYNOPSIS 🌸

enum nvme_id_ctrl_cntrltype {
    NVME_CTRL_CNTRLTYPE_IO ,
    NVME_CTRL_CNTRLTYPE_DISCOVERY ,
    NVME_CTRL_CNTRLTYPE_ADMIN

};

no cap, that's the entire thing. three constants, zero drama. 🦋

🎀 Constants 🎀

these are the three flavors of controller, mwah:

• NVME_CTRL_CNTRLTYPE_IO — NVM I/O controller. she does the actual input/output work, the main character of data movement. 🔥
• NVME_CTRL_CNTRLTYPE_DISCOVERY — Discovery controller. she's the one who tells you what's out there, like a group chat that knows everyone's whereabouts. 🔍✨
• NVME_CTRL_CNTRLTYPE_ADMIN — Admin controller. admin energy only, running the place. 👑

ngl there are exactly three of these and you now know all three, so congrats, you've officially aced this page. 🌈⭐
