💫 ror16(9) 💫

okay so welcome to the kernel API manual bestie, we're doing ror16 today and honestly? she's iconic. tiny function, huge main character energy. this is the page for rotating a 16-bit value right 🎀

---

✨ NAME ✨

ror16 — rotate a 16-bit value right. that's it. that's the whole gig. no cap 💅

---

🦋 SYNOPSIS 🦋

__u16 ror16 (__u16 word , unsigned int shift );

look at her. so simple. so clean. she takes two things and gives you back a __u16, periodt ✨

---

🌸 ARGUMENTS 🌸

• word — the value to rotate. this is your lil guy going in for the spin 💖
• shift — the bits to roll. how far right are we yeeting it, iykyk 🔥

👑 SEE ALSO 👑

okay so if you liked this one (and you did, obviously), the kernel file ./include/linux/bitops.h has the whole friend group 🫶. lowkey it's giving bit-twiddling royalty:

• rol64(9)
• ror64(9)
• rol32(9)
• ror32(9)
• rol16(9)
• rol8(9)
• ror8(9)
• sign_extend32(9)
• sign_extend64(9)
• get_count_order_long(9)
• parity8(9)
• __ffs64(9)
• fns(9)
• assign_bit(9)
• __ptr_set_bit(9)
• __ptr_clear_bit(9)
• __ptr_test_bit(9)

literally the entire bitops squad, go read them all, they ate 💀✨

ngl bestie, shift is unsigned int and word is __u16 — keep those types exactly how they are, the kernel does not play about types 🙈

and that's the page!! mwah 💖 this one lives over in ./include/linux and it's dated October 2026 — so yeah, mark your calendar, she's from the future, iconic behavior honestly 👑🌈⭐
