LIBNVME_SUBSYSTEM_FOR_EACH_CTRL_SAFE-LIBNVME3(2)

💖 NAME 💖

libnvme_subsystem_for_each_ctrl_safe — bestie, this one is literally just "Traverse controllers" 🎀 like it walks through them, no cap

✨ SYNOPSIS ✨

libnvme_subsystem_for_each_ctrl_safe (s , c , _c );

Three args, in that exact order, three little commas doing their thing 🦋

🌸 ARGUMENTS 🌸

• s — your struct libnvme_subsystem object, the main character of this whole operation 👑
• c — the controller instance, aka the one you're actually lookin' at right now 💅
• _c — a struct libnvme_ctrl node that you're just gonna use as temporary storage 🫶 lowkey it's the safe-traversal helper, the little scratchpad holding your place so nothing gets weird mid-loop

okay so quick vibe check: s is the subsystem, c is the controller you're reppin', and _c is your temp node for storage — that's the whole trio, don't @ me 😭

that's the whole page, bestie, we ate and left no crumbs 🍓 ngl it's short and iconic — from the libnvme API manual, dated October 2026, and the page goes by libnvme_subsystem_for_each_ctrl_safe(9) up in the header and libnvme_subs...ch_ctrl_safe(9) down in the footer. mwah 💜✨
