💅 cs_dsp_chunk_write(9)

okay bestie, welcome to the Kernel API Manual ✨ this one's all about cs_dsp_chunk_write — the lil function that formats your data into a DSP memory chunk 🎀

🌸 NAME 🌸

cs_dsp_chunk_write — formats data to a DSP memory chunk, no cap 💖

🦋 SYNOPSIS 🦋

int cs_dsp_chunk_write (struct cs_dsp_chunk *ch , int nbits , u32 val );

✨ ARGUMENTS ✨

  • ch — pointer to the chunk structure, like the little container bestie you're writing into 🫶
  • nbits — how many bits you wanna write, literally the bit count 💅
  • val — the value you're writing, the actual content, the main character of this whole operation 👑

💜 DESCRIPTION 💜

So here's the vibe: this function sequentially writes values into the format required for DSP memory. She's doing double duty — handling the inserting of the padding bytes and converting to big endian, and she does it all without breaking a sweat 😭🔥

⚠️ but bestie, listen — data is only committed to the chunk when a whole DSP words worth of data is available. like, she's not gonna half-commit, that's not her energy. whole word or nothing, periodt 💀

🌈 RETURN 🌈

  • Zero for success 🎉
  • a negative number on error 😭
