📦 version 3.2, in arch rolling

✨ libnvme_get_ctrl_attr 💅

Okay bestie, welcome to the libnvme API manual — this one's a little function with main character energy and it's gonna read a sysfs attribute off your controller and hand it to you in a shiny new string. Let's go 🫶

🌸 NAME 🌸

libnvme_get_ctrl_attr — literally just read a controller sysfs attribute. That's the whole vibe. 📖✨

🦋 SYNOPSIS 🦋

char * libnvme_get_ctrl_attr (struct libnvme_ctrl *c , const char *attr
);

So you pass in a controller and an attribute name, and it hands you back a char *. Iconic signature, no notes. 👑

🎀 ARGUMENTS 🎀

  • c — your controller instance. Yeah, the actual controller you're obsessed with. Gotta tell her which one. 🎯
  • attr — the sysfs attribute name. That's the thing you're reaching for, bestie. Point at it and she'll go get it. 🔍

💖 RETURN 💖

So here's what you get back:

  • A newly allocated string holding the contents of attr — and listen, the caller frees it. That's you. You're the caller. It's your string now, bestie, take care of it 🫶
  • Or NULL in case of an empty value or an error. Ngl, NULL is kind of a mood, but you gotta check for it. 😭
No cap: don't forget to free that string. It's freshly allocated and it's all yours 💀
