🎀 NAME 🎀

ndelay — inserting a delay based on nanoseconds with busy waiting 🌀

like, yes, the kernel will just sit there spinning while the nanoseconds tick by. no sleeping, no napping, no vibe check on the scheduler. it's giving "spin class" energy 🔥

void ndelay (unsigned long nsec );

---

🦋 ARGUMENTS 🦋

• nsec — the requested delay, measured in nanoseconds ⏱️✨ (it's an unsigned long, so be normal about it)

💖 DESCRIPTION 💖

so this page is lowkey a redirect, ngl — for the basics about ndelay and it's variants, you wanna go read udelay. that's the main character of this little delay family 👑 go check it out, iykyk.
