libnvme_tra...submit_entry(9)

💅 libnvme_transport_handle_set_submit_entry(9) ✨

okay so bestie, welcome to the libnvme API manual — this one's called libnvme_tra...submit_entry(9) (yes the title's a little truncated, she's shy, it's giving ellipsis energy 🫶). Let's get into it.

---

🌸 NAME 🌸

libnvme_transport_handle_set_submit_entry — install a submit-entry callback. literally what it says on the tin 💖

---

🎀 SYNOPSIS 🎀

void libnvme_transport_handle_set_submit_entry (struct
libnvme_transport_handle *hdl , void *(*submit_entry)(struct
libnvme_transport_handle *hdl, struct libnvme_passthru_cmd *cmd) );

no cap, that's the whole signature. copy it exactly, don't get cute with the spacing 😭

---

🦋 ARGUMENTS 🦋

• hdl — the transport handle you're configuring. she's the main character here, you gotta hand her over.
• submit_entry — the callback, invoked immediately before a passthrough command is submitted. the function receives the command that's about to be issued and may return an opaque pointer representing per-command context. that pointer is later passed unmodified to the submit-exit callback. implementations typically use this hook for logging, tracing, or allocating per-command state. it's giving very useful, very iconic 💅

---

⭐ DESCRIPTION ⭐

so basically: this installs a user-defined callback that gets invoked at the moment a passthrough command enters the NVMe submission path. 🔥

and here's the important bit — passing NULL removes any previously installed callback. poof, gone, she's deleted 🙈

---

👑 RETURN 👑

None. that's it. nothing comes back. void queen behavior 💀

---

🌈 SEE ALSO 🌈

okay there's no SEE ALSO section in this one bestie, we're keeping it 100 — nothing to cross-reference here 🧚

---

💜 a lil reminder: keep those callback pointers honest and remember NULL is your uninstall button. no take-backs otherwise.

and that's a wrap, bestie! 🎀 this icon was brought to you by the libnvme API manual, dated October 2026 — source/version and all 💖 slay, read responsibly, and may your passthrough commands always submit on time ✨🦋💅
