✨ nvmf_update_config(2) ✨

okay bestie, gather round, because today we're talking about nvmf_update_config from the libnvme API manual 💖 it's a lil function, it's a good function, and it does exactly one thing. no cap.

🌸 NAME 🌸

nvmf_update_config — update fabrics configuration values 🧚

like. that's it. that's the whole job. it updates the fabrics config values. slay.

---

🎀 SYNOPSIS 🎀

void nvmf_update_config (nvme_ctrl_t c , const struct
nvme_fabrics_config *cfg );

notice how it returns void? yeah. she gives nothing back. she just does. main character energy fr fr 💅

---

🦋 ARGUMENTS 🦋

• c — the Controller to be modified 👑 this is the one getting a glow-up.
• cfg — the Updated configuration values ✨ this is the one holding the new lewk.

two args. one victim, one makeover kit. iconic.

---

💜 DESCRIPTION 💜

so here's the tea 🍵 nvmf_update_config updates the values from c with the configuration values from cfg. all non-default values from cfg will overwrite the values in c.

and yes bestie, read that again: all non-default values from cfg will overwrite the values in c. so if cfg is sitting there with a default in some field, it is NOT gonna touch your controller. defaults are shy like that 🙈 but anything in cfg that's been set to something non-default? it's coming in and it's taking over. periodt.

so like, lowkey think of it as: cfg is the moodboard, c is the outfit, and only the pieces cfg actually picked get swapped in. the defaults stay home. 🌈

ngl this is a mutation function — c gets changed in place. there's no return value to check, no error to catch. it just goes. so make sure c is actually the controller you meant, bestie 😭
