snd_sgbuf_get_chunk_size(9)

✨ NAME ✨

okay bestie, welcome to the Kernel API Manual entry for snd_sgbuf_get_chunk_size(9) 🫶. This icon computes the max chunk size with continuous pages on an sg-buffer — yes, it's giving buffer math realness, and we're obsessed 💅✨.

🦋 SYNOPSIS 🦋

unsigned int snd_sgbuf_get_chunk_size (struct snd_dma_buffer *dmab ,
unsigned int ofs , unsigned int size );

🎀 ARGUMENTS 🎀

• dmab — buffer allocation information. It's basically the buffer's receipts, bestie 🧾.
• ofs — offset in the ring buffer. Yes, the ring buffer — not a jewelry ring, sadly 💍.
• size — the requested size. That's the size you're asking for, periodt 🌸.

💫 RETURN 💫

it returns the chunk size. That's it, that's the tea ☕✨.
