💅 k3_ringacc_ring_pop_tail — like, the whole page

okay so real talk, this is a page out of the Kernel API Manual, and it's about one tiny little function that pops a thing off the tail end of a ring. yes. that's the whole plot. but it's iconic and we're gonna learn it 💖

✨ NAME ✨

k3_ringacc_ring_pop_tail — pop element from the ring tail 🎀

🌸 SYNOPSIS 🌸

int k3_ringacc_ring_pop_tail (struct k3_ring *ring , void *elem );

🦋 ARGUMENTS 🦋

  • ring — pointer on ring. yes bestie, it's a pointer on the ring, that's the wording, we don't argue with the wording 🫶
  • elem — pointer on ring element buffer. this is where the popped element ends up, so hand it somewhere real to live.

🔥 DESCRIPTION 🔥

Push one ring element from the ring tail. (no bc that is literally what the page says, and I am not out here editing the docs, iykyk 😭💀)

The size of the ring element is determined by the ring configuration struct k3_ring_cfg — specifically its elm_size field. so like, the ring already knows how big its elements are, you don't gotta tell it. main character energy fr ✨

It returns 0 on success, or errno otherwise. ngl, errno on a bad day. 🙈

⚠️ Not Supported by ring modes: K3_RINGACC_RING_MODE_RING. if your ring is in that mode, this function is not it. hard pass. 💀
