πŸ“¦ version 3.2, in arch rolling

πŸ’… libnvmf_context_create β€” from the libnvme API manual, bestie

okay so this is <pink>libnvmf_context_create</pink> from the <purple>libnvme API manual</purple> β€” yes it's a <kbd>9</kbd> (kernel-adjacent, section 9, we're fancy like that) and it's the moment where your NVMe-oF fabrics journey begins, no cap πŸŽ€


✨ NAME ✨

libnvmf_context_create β€” make a brand new <hotpink>fabrics context</hotpink> for discovery/connect πŸ¦‹


✨ SYNOPSIS ✨

int libnvmf_context_create (struct libnvme_global_ctx *ctx ,
                            bool (*decide_retry)(struct libnvmf_context *fctx, int err, void *user_data) ,
                            void (*connected)(struct libnvmf_context *fctx, struct libnvme_ctrl *c, void *user_data) ,
                            void (*already_connected)(struct libnvmf_context *fctx, struct libnvme_host *host,
                                                      const char *subsysnqn, const char *transport,
                                                      const char *traddr, const char *trsvcid, void *user_data) ,
                            void *user_data ,
                            struct libnvmf_context **fctxp );

like, look at all those function pointers. that's six-ish arguments and <rainbow>four of them are callbacks</rainbow> β€” she's high-maintenance but she's worth it πŸ’…


✨ ARGUMENTS ✨

  • ctx β€” the global context. your main character. everything hangs off her πŸ‘‘
  • decide_retry β€” hook that decides whether a retry should even be attempted. it's giving "let me think about it" energy πŸ™ˆ
  • connected β€” hook that gets invoked when a connection is established. <mint>slay, you're in</mint> ✨
  • already_connected β€” hook invoked if you're already connected. lowkey the "you're already on the list, babe" moment πŸ’€
  • user_data β€” your user data, passed straight through to the hooks. it's the little bag you hand off to every callback so they all know what's up 🫢
  • fctxp β€” pointer to store the created context. she goes in here πŸŽ€

✨ DESCRIPTION ✨

libnvmf_context_create allocates and initializes a new <hotpink>fabrics context</hotpink> for discovery/connect operations. that's the whole bit β€” allocate it, init it, hand you back a context you can actually do stuff with. <purple>obsessed</purple> πŸ’œ


✨ RETURN ✨

returns 0 on success, and a <red>negative error code</red> otherwise. <yellow>check it, fr fr β€” zero is the slay outcome, negative means something went sideways 😭


bestie reminder: 0 = good vibes, negative = go read the error code πŸ”₯

so yeah, that's the whole page πŸ’– written by <lavender>libnvme API manual</lavender>, from <blue>libnvmf_context_create(9)</blue>, dated <green>October 2026</green> β€” mwah, go create some contexts, you've got this 🧚🌸
