parport_ip3...te_block_dma(9)

📦 version 7.3.1, in nixpkgs unstable

💖 parport_ip32_fifo_write_block_dma (9) 💖

okay so real talk: this is from the Kernel API Manual, section 9, and the header up top is literally just the function name getting its hair done at the salon (the terminal chopped it into parport_ip3...te_block_dma(9), iconic of it honestly). Bestie, we're about to write a whole block of data into a parallel port FIFO using DMA, and you're gonna understand every bit of it. periodt. 🎀

✨ NAME ✨

parport_ip32_fifo_write_block_dma — write a block of data (DMA mode) 🦋

🌸 SYNOPSIS 🌸

size_t parport_ip32_fifo_write_block_dma (struct parport *p , const void
*buf , size_t len );

she takes three things, she gives you back a size_t. that's the whole vibe check. 💅

💜 ARGUMENTS 💜

  • p — pointer to struct parport. the parallel port in question, the main character. 🔥
  • buf — buffer of data to write. this is the stuff, the payload, the actual tea being spilled into the FIFO. 🍓
  • len — length of buffer buf. how much of it we're sending, not a byte more. 📏

⭐ DESCRIPTION ⭐

Uses DMA to write the contents of the buffer buf into the parallel port FIFO. Returns the number of bytes that were actually written. 👑

yes bestie, actually — so like, don't assume it ate all len bytes, check the return value, that's the whole point. 🫶

⚠️ heads up, and this is not a drill: the parallel port must be correctly initialized before calling parport_ip32_fifo_write_block_dma. no init, no write. that's the rule. 💀
