SCU_GET_FRAME_INDEX(9)

💅 SCU_GET_FRAME_INDEX(9) — like, the Kernel API Manual edition, bestie ✨

okay so real talk, this is a page straight out of the Kernel API Manual and it's giving "tiny macro, huge responsibility" energy. buckle up 🎀

---

✨ NAME ✨

SCU_GET_FRAME_INDEX — and honestly the official NAME line doesn't even give us a description after the dash, so like... that's the whole name section. no cap. we move 💀

---

🌸 SYNOPSIS 🌸

SCU_GET_FRAME_INDEX (completion_code );

that's it. that's the whole call. one argument, one macro, zero drama (mostly) 🦋

---

🎀 ARGUMENTS 🎀

• completion_code — sooooo the original manpage literally says "-- undescribed --" for this one 😭 like the docs team just left it blank and dipped. bestie i'm not gonna invent a description for you because that would be lying and we don't do that here. it's the completion code. that's all we've got. iykyk 🙈

---

💜 DESCRIPTION 💜

okay so here's the tea: this macro returns a normalized frame index from an unsolicited frame completion. that's the whole vibe. it takes your completion and hands you back a tidy, normalized frame index, periodt ✨
