💅 cs_dsp_read_data_word(9) — a Kernel API Manual moment

okay bestie, welcome to the cs_dsp_read_data_word page, straight out of the Kernel API Manual and honestly? it's giving "tiny function, big responsibility" energy. she reads a word from DSP memory. that's it. that's the whole vibe. 🎀

✨ NAME ✨

cs_dsp_read_data_word — Reads a word from DSP memory 🫶

🌸 SYNOPSIS 🌸

int cs_dsp_read_data_word (struct cs_dsp *dsp , int mem_type , unsigned
int mem_addr , u32 *data );

like yes, that's the whole signature, no cap. four args, one int coming back atcha. 💖

🦋 ARGUMENTS 🦋

  • dsp — pointer to DSP structure. literally the main character here, she's the DSP we're talking to ✨
  • mem_type — the type of DSP memory containing the data to be read. iykyk, different memory regions, and this tells us which one we're poking 👀
  • mem_addr — the address of the data within the memory region. like the exact spot. the coordinates. the address-address 📍
  • data — a buffer to store the fetched data. she catches the word for you, put her somewhere safe 🧺

⭐ RETURN ⭐

Zero for success 🌈, a negative number on error 💀. that's it, that's the contract, no surprises.

fr fr check that return value, bestie — negative means something went sideways and you should not be out here pretending it slayed 🙈

🔥 SEE ALSO 🔥
