libnvmf_config_emit_add(9)

💅 libnvmf_config_emit_add — libnvme API manual, bestie edition 🎀

okay so bestie, welcome to libnvmf_config_emit_add(9), literally the libnvme API manual page you didn't know you needed. sit down, grab a strawberry drink 🍓, and let's get into it.

✨ NAME ✨

libnvmf_config_emit_add — add a connection to a configuration emitter. that's it. that's the whole vibe. 🫶

---

🌸 SYNOPSIS 🌸

int libnvmf_config_emit_add (struct libnvmf_config_emitter *emitter ,
bool is_dc , const char *transport , const char *traddr , const char
*trsvcid , const char *subsysnqn , const char *host_traddr , const char
*host_iface , const char *hostnqn , const char *hostid , const struct
libnvmf_params *params , const char *hostsymname );

look at that signature. she's long. she's iconic. she ate. 🔥 (and yes, copy it exactly, character for character — no cap, we don't edit signatures around here)

---

🦋 ARGUMENTS 🦋

• emitter — the configuration emitter. your main character, honestly. 👑
• is_dc — discovery controller if true, I/O controller if false. pick your fighter.
• transport — transport type. required. no skipping, babe.
• traddr — transport address. required. written verbatim, even if it's a hostname — like, resolution happens at connect time, not here. it's giving "not my job, not my problem" 💅
• trsvcid — transport service ID, or NULL.
• subsysnqn — subsystem NQN. required unless is_dc is true. read that twice, bestie 😭
• host_traddr — host transport address, or NULL.
• host_iface — host interface, or NULL.
• hostnqn — host NQN, or NULL.
• hostid — host identifier, or NULL.
• params — connection parameters, or NULL.
• hostsymname — host symbolic name, or NULL.

---

🌈 DESCRIPTION 🌈

so the parameter set? the emitter copies it. yes, copies. it takes what you gave it and keeps its own little version. lowkey polite of it. ✨

---

💀 RETURN 💀

• 0 — on success. slay. we love to see it 💖
• -EINVAL — if a required parameter is missing, or if hostsymname conflicts with an existing persona. bestie that's a whole identity crisis, go fix it 🙈
• -ENOMEM — if memory allocation fails. the malloc said no. 😭

heads up: those required parameters are required — transport and traddr always, and subsysnqn too unless is_dc is true. the function will absolutely hand you an -EINVAL and you will deserve it. 🫶

that's the whole page, diva. go forth and emit some connections 🧚‍♀️💜
