STRING_BENCH(9)

okay so bestie, welcome to the STRING_BENCH(9) glow-up from the Kernel API Manual — it's giving benchmark-string-functions energy and we are obsessed 💖✨

✨ NAME ✨

🦋 SYNOPSIS 🦋

STRING_BENCH (iters , func , ... );

💅 ARGUMENTS 💅

• iters — Number of iterations to run. 🔁
• func — Function to benchmark. 🧪

🌸 DESCRIPTION 🌸

Okay so this disables preemption and measures the total time in nanoseconds to execute func(__VA_ARGS__) for iters times — including a small warm-up phase, because we warm up before we slay 🔥

⭐ CONTEXT ⭐

Disables preemption during measurement. That's the whole context, no cap 💀

👑 RETURN 👑

Total execution time in nanoseconds (u64). That's the number, bestie — an actual u64 👑
