libnvmf_register_ctrl — Perform registration task with a DC 🦋

✨ SYNOPSIS ✨

int libnvmf_register_ctrl (struct libnvme_ctrl *c , enum nvmf_dim_tas
tas , __u32 *result );

✨ ARGUMENTS ✨

• c — Controller instance. your main character, the controller we're doing the thing to 💜
• tas — Task field of the Command Dword 10 (cdw10). it tells the command whether to do a Registration, a Deregistration, or a Registration-update. literally the vibe check of the whole call 🌸
• result — The command-specific result returned by the DC upon command completion. where the answer lands once the DC finishes up 🫶

✨ DESCRIPTION ✨

Perform registration task with a Discovery Controller (DC). 💫

Three tasks are supported, and we're listing them all, no skipping:

• register
• deregister
• registration update

that's the whole menu, periodt. 🔥

✨ RETURN ✨

0 on success, negative error code otherwise. so like — zero is the slay outcome, anything negative means something went sideways 😭

---

ngl, if you get a negative number back, that's your sign to check the vibes (and the error code) before trying again 🙈
