libnvme_ns_get_ctrl(9)

πŸ“¦ version 3.2, in arch rolling

πŸ’… libnvme_ns_get_ctrl β€” a whole manual page, bestie

okay so this is a page from the libnvme API manual, and it's about libnvme_ns_get_ctrl(9) β€” yes the (9) is part of the name, it's giving kernel-section realness. sit down, grab a strawberrry drink πŸ“, and let's get into it.


✨ NAME ✨

libnvme_ns_get_ctrl β€” grab the &struct libnvme_ctrl of a namespace πŸŽ€

like, you have a namespace, and you want its controller. that's the whole vibe.


🌸 SYNOPSIS 🌸

struct libnvme_ctrl * libnvme_ns_get_ctrl (struct libnvme_ns *n );

literally the whole function right there. no cap.


πŸ¦‹ ARGUMENTS πŸ¦‹

  • n β€” the namespace instance πŸ’– (this is your girl, the one you're asking about)

πŸ’€ DESCRIPTION πŸ’€

so here's the tea: the struct libnvme_ctrl object may be NULL for a multipathed namespace. 😭

that's it. that's the whole description. not me getting emotional over a possible NULL return. main character energy from a pointer, honestly.

⚠️ bestie please check for NULL before you dereference, i am begging 🫢

πŸ‘‘ RETURN πŸ‘‘

it hands you back the struct libnvme_ctrl object of n if present ✨

if it's not present… you already know. NULL. πŸ’…


🌈 that's a wrap 🌈

that was libnvme_ns_get_ctrl(9) from the libnvme API manual, dated October 2026 β€” go forth and get your controllers, icon, and don't forget the NULL check πŸ§šπŸ’œ πŸŽ€
