libnvmf_create_ctrl(9)

πŸ“¦ version 3.2, in arch rolling

πŸ’– libnvmf_create_ctrl β€” the libnvme API manual, but make it a group chat

okay so bestie, welcome to libnvmf_create_ctrl(9) πŸŽ€ β€” this is the libnvme API manual page for libnvmf_create_ctrl, and yes the name is a mouthful but we're gonna get through it together. it's giving "small function, big feelings" lowkey.


✨ NAME ✨

libnvmf_create_ctrl β€” allocate an unconnected NVMe controller πŸ¦‹

like, it makes you a controller that isn't connected to anything yet. a baby controller. a controller in its "finding itself" era. no cap.


✨ SYNOPSIS ✨

int libnvmf_create_ctrl (struct libnvme_global_ctx *ctx , struct
libnvme_context *fctx , struct libnvme_ctrl **c );

yup, returns an int, takes three args. slay. ✨


✨ ARGUMENTS ✨

  • ctx β€” a struct libnvme_global_ctx object πŸ’œ your global context bestie, the big-picture one.
  • fctx β€” the Fabrics context 🌸 this one's carrying the connection tea.
  • c β€” a struct libnvme_ctrl object to return 🫢 like, this is where the new controller gets handed back to you.

✨ DESCRIPTION ✨

so what it does πŸ‘‘ β€” it creates an unconnected controller, and that controller is meant to be used for libnvme_add_ctrl. that's the whole vibe. main character energy, but the plot is "get added later".

and here's the part you gotta know, fr fr: the controller carries over fctx's connection parameters together with its authentication and transport encryption settings πŸ”₯ β€” and to be super specific, that means the kxchap keys, the keyring, the TLS key, and the TLS key identity. all of that comes along for the ride. it's giving "bring your whole friend group to the party" πŸ’…


✨ RETURN ✨

  • 0 on success πŸŽ‰ periodt.
  • a negative error code otherwise 😭 (iykyk β€” check it, don't ignore it).
okay but seriously, always vibe check that return value. negative means something went wrong and you don't wanna find out later the hard way πŸ’€

and that's the page bestie!! 🌈 written in October 2026, from the libnvme API manual, and yeah β€” this whole thing is literally libnvmf_create_ctrl(9) all the way down πŸ’–πŸ§šβ­
