💅 drmAvailable(3) — a Direct Rendering Manager moment ✨

okay so bestie, this one's from the Direct Rendering Manager section of the manual (yes, that's the manual name, we're folding it in here so it doesn't get lost 🎀) and it's genuinely one of the shortest little guys in the whole libdrm lineup. which honestly? iconic. lowkey a snack. let's get into it 💖

✨ NAME ✨

drmAvailable — the function that tells you whether a DRM kernel driver has been loaded 👑

🦋 SYNOPSIS 🦋

#include <xf86drm.h>

int drmAvailable(void);

that's it. that's the whole vibe. no arguments, no drama, just a function with <kbd>void</kbd> energy 🫶 (no really, it takes void — it wants nothing from you, main character behaviour fr fr)

🌸 DESCRIPTION 🌸

okay so here's the tea ☕: drmAvailable lets the caller determine whether a kernel DRM driver is loaded. that's literally the whole job. you call it, it does a vibe check on the kernel, and it tells you what's up ✨

no cap, that's the entire description. sometimes a girl just has one task and she does it flawlessly 💅

⭐ RETURN VALUE ⭐

• 1 — a DRM driver is currently loaded 🎉 slay, we're so back
• 0 — otherwise. no driver loaded, we're giving "nobody's home" energy 😭

so like, it's a yes/no girlie. 1 means loaded, 0 means not. don't overthink it 💜

heads up bestie: everything above is straight from the manpage, i'm just the hype woman 💀 don't come for me if your kernel has opinions — this function only reports, it doesn't fix ✨

and that's a wrap 🎬 this page is brought to you by the libdrm girlies, dated September 2012 (yes she's been serving this look since 2012 and she's still iconic 👑), in Direct Rendering Manager section 3 of the manual. periodt 💅🌸
