qman_is_probed(9)

💅 qman_is_probed(9) — like, the Kernel API Manual, but make it cute

okay so bestie, welcome to qman_is_probed — yes that's the whole name, yes it's a mouthful, no we're not changing it. This is the page for the lil function that checks if qman is probed. That's it. That's the vibe. 🎀

✨ NAME ✨

qman_is_probed — check if qman is probed 👀

🦋 SYNOPSIS 🦋

int qman_is_probed (void );

🌸 ARGUMENTS 🌸

• void — no arguments, bestie. it takes literally nothing. zero. nada. it's giving "i need no input, i simply know" 💅

🔥 DESCRIPTION 🔥

okay so this is the whole tea: qman_is_probed returns a number, and that number is your entire vibe check on the qman driver. here's the breakdown 🫶

• 1 — the qman driver successfully probed. slay. it's up, it's alive, it ate. 👑
• -1 — the qman driver failed to probe. 😭 not the vibe. something went wrong.
• 0 — the qman driver did not probe yet. it's not a no, it's a "not yet" — it's still loading, give it a sec. ⏳

that's it. three possible answers. no cap, that's the whole function.

ngl this one's a short page but it's iconic in its own lowkey way — if you're calling anything else in this family you probably want to know which of these three states you're in first. fr fr. 🧚
