LIBNVME_MI_EP_SET_SUBMIT_ENTRY-LIBNVME3(2)

💅 libnvme_mi_ep_set_submit_entry 💅

okay so bestie, welcome to the libnvme API manual — specifically libnvme_mi_ep_set_submit_entry(9), which lowkey has main character energy for reasons we're about to get into. no cap, this one's a little gem.

✨ NAME ✨

libnvme_mi_ep_set_submit_entry — install the MI submit-entry callback 🎀

like, literally install it. it's giving "set it and forget it" but make it C.

---

🦋 SYNOPSIS 🦋

here's the whole vibe, verbatim:

void libnvme_mi_ep_set_submit_entry (struct libnvme_mi_ep *ep , void
*(*mi_submit_entry)(struct libnvme_mi_ep *ep, __u8 type, const struct
nvme_mi_msg_hdr *hdr, size_t hdr_len, const void *data, size_t data_len)
);

yeah the signature is a whole paragraph. we don't gatekeep, we just cope. 💀

🌸 ARGUMENTS 🌸

• ep — the endpoint you're configuring. that's your girl. that's who you're setting up. 🫶
• mi_submit_entry — okay so this is the callback itself, and here's the tea ☕: after input validation happens, this callback gets invoked before an MI command is submitted. it receives the endpoint, message type, header, and data about to be sent — the whole little care package. and the fun part? it may return an opaque pointer representing per-command context. that pointer later gets passed unmodified to the mi_submit_exit callback. so if you're a "keep track of my stuff" girly, this is your moment.

implementations typically use this hook for logging, tracing, or allocating per-command state. very much "notes app" behavior but for C structs. iconic. ✨

---

💖 DESCRIPTION 💖

so what does this actually do? it installs a callback that gets invoked at the moment an MI command enters the submission path. 🎯

this applies to all MI operations through this endpoint — both endpoint-level MI commands and controller admin commands. so like, no sneaky exceptions, no "except this one thing" betrayal. it's consistent. we love consistency.

heads up bestie: passing NULL removes any previously installed callback. yes, it's the uno-reverse card of callbacks. 💅

that's the whole page, no filler, no fluff, fr fr. 🔥
