thc_rxdma_read(9)

🌸 thc_rxdma_read(9) 🌸

okay bestie, welcome to the Kernel API Manual, section 9 💅 this one's a read function and it's kind of a big deal, so let's get into it 🫶

---

✨ NAME ✨

thc_rxdma_read — literally just Read data from RXDMA buffer 📖✨ that's the whole vibe.

---

🦋 SYNOPSIS 🦋

int thc_rxdma_read (struct thc_device *dev , enum thc_dma_channel
dma_channel , void *read_buff , size_t *read_len , int *read_finished );

---

🎀 ARGUMENTS 🎀

• dev — the pointer of THC private device context. yep, your main character struct 💜
• dma_channel — the RXDMA engine of read data source. it's giving "where the tea comes from" ☕
• read_buff — the pointer of the read data buffer. the little container your data lands in 🍓
• read_len — the pointer of the read data length. how much we're reading, noted and slayed 📏
• read_finished — the pointer of the flag indicating if all pending data has been read out. that's the "are we done here or what" flag 👑 no cap, once it says everything's drained, you're done.

---

🔥 RETURN 🔥

0 on success, other error codes on failed. simple as that, periodt 💀

fr fr bestie, check your return value. 0 is the slay outcome, anything else means something went sideways and you should deal with it 🙈
