errseq_check(9) 🔥

okay so this is the Kernel API Manual page for errseq_check(9), and we're literally about to check whether an error happened since a particular sample point. bestie, let's get into it. ✨

🌸 NAME 🌸

errseq_check — Has an error occurred since a particular sample point? 😭

✨ SYNOPSIS ✨

int errseq_check (errseq_t *eseq , errseq_t since );

🎀 ARGUMENTS 🎀

• eseq — pointer to the errseq_t value that's getting checked. 👀
• since — the previously-sampled errseq_t you're checking from; it's your little "before" snapshot. 🦋

💅 DESCRIPTION 💅

So here's the tea: it grabs the value that eseq points to, then sees if it has changed since the given value was sampled. The since value is not advanced, so there is literally no need to mark the value as seen. Periodt. 💖

⭐ RETURN ⭐

It returns the latest error set in the errseq_t, or 0 if it hasn't changed. That's it, icon. 🔥
