LIBNVME_CTRL_GET_COMMAND_ERROR_COUNT-LIBNVME3(2)

📦 version 3.2, in arch rolling

💅 libnvme_ctrl_get_command_error_count — the libnvme API manual, bestie edition ✨

Okay so this one lives in the libnvme API manual, section 9, and it's genuinely one of the shorter ones — a little getter function that goes and fetches the command_error_count for you. Lowkey iconic, no cap. Let's get into it 🫶

🌸 NAME 🌸

libnvme_ctrl_get_command_error_count — literally just: get command_error_count. That's the whole vibe check. 🎀

✨ SYNOPSIS ✨

int libnvme_ctrl_get_command_error_count (const struct libnvme_ctrl *p ,
long *command_error_count , long dflt );

Look at her. Clean. Minimal. Main character energy 💅

🦋 ARGUMENTS 🦋

  • p — the struct libnvme_ctrl instance you're querying. Like, the actual controller you want deets about. Give her a pointer and she'll do the rest.
  • command_error_count — where to store the value on success 👑 this is the output spot, okay? That's where the good stuff lands.
  • dflt — the value to store in command_error_count on failure. So if things go sideways, at least you're not left staring at garbage memory — you get this fallback instead. Safety net behavior, we love to see it 🙈✨

🔥 RETURN 🔥

  • 0 on success — slay, it worked 💖
  • -ENOENT if the attribute does not exist — that thing is simply not there, not me making it up 😭
  • any other negative errno on failure — something else went wrong, check your errno fr fr

🌈 A lil sign-off 🌈

That's the whole page, bestie — short and sweet, just how we like her. This one comes from the libnvme docs, dated October 2026, and the manual page tag is libnvme_ctrl..._error_count(9). Go get those error counts, you gorgeous nerd 🧚⭐💜
