libnvme_wait_passthru(9)

📦 version 3.2, in arch rolling

💅 libnvme_wait_passthru 💅

okay so bestie, welcome to the libnvme API manual — this one's a cute lil function called libnvme_wait_passthru, and honestly? she's the responsible friend who makes sure everyone gets home safe. 🫶

🌸 NAME 🌸

libnvme_wait_passthru — literally just wait for all pending passthru completions. that's it. that's the whole vibe. no cap. ✨

🎀 SYNOPSIS 🎀

int libnvme_wait_passthru (struct libnvme_transport_handle *hdl );

like yes that's the whole signature, she's not complicated, she's just iconic. 💜

🦋 ARGUMENTS 🦋

  • hdl — the transport handle. your main character struct, the one carrying all the context. you hand her over and she does her thing. 🎀

🧚 DESCRIPTION 🧚

so here's the tea ☕ — libnvme_wait_passthru drains all pending passthru commands from the async queue. think of it like clearing the group chat notifs: everything that was sitting there waiting gets dealt with, periodt. 💀

the move is to call this after batching multiple libnvme_submit_admin_passthru calls — but only when io_uring is enabled. that's the whole window where this makes sense, iykyk. if you're not on io_uring, this is not your era. 🙈

fr fr though — batch your submits first, then come drain them here. that's the order. don't skip steps, bestie. 😭

⭐ RETURN ⭐

  • 0 on success — slay, everything drained clean, we love to see it 👑
  • or the first non-zero status encountered — so if something went sideways, she reports the first problem she hit, not a whole messy pile. one drama at a time, we respect it. 🔥

🌈 a lil sign-off 🌈

this page came from the libnvme API manual, dated October 2026, and it's all about libnvme_wait_passthru — the same name three times over because consistency is a flex. 💅✨ go drain those queues, queen. 🦋
