✨ xilinx_aximcdma_alloc_tx_segment(9) ✨

okay so real talk, bestie — this page lives in the Kernel API Manual, and its cute lil running header is xilinx_aximc...c_tx_segment(9) (yes the header is out here looking truncated and mysterious, we love an abbreviation era 💅). Anyway. Let's get into it 🫶

---

🌸 NAME 🌸

xilinx_aximcdma_alloc_tx_segment — literally just: allocate a transaction segment. That's the whole vibe. ✨

---

🦋 SYNOPSIS 🦋

struct xilinx_aximcdma_tx_segment * xilinx_aximcdma_alloc_tx_segment
(struct xilinx_dma_chan *chan );

like, copy that exactly, no cap. 🎀

---

💖 ARGUMENTS 💖

• chan — the driver specific DMA channel. that's her. she's the one you're handing over. 👑

---

⭐ RETURN ⭐

The allocated segment on success, and NULL on failure 😭. so like… check it. pls check it. i'm begging. 🙈
