✨ snd_hdac_bus_get_response ✨

okay bestie, welcome to the Kernel API Manual 💖 this one is short and sweet, and honestly? iconic behavior.

🌸 NAME 🌸

snd_hdac_bus_get_response — receive a response via RIRB or PIO 💅

like, you sent a command, and now you want the reply. that's the whole vibe. 🦋

🎀 SYNOPSIS 🎀

int snd_hdac_bus_get_response (struct hdac_bus *bus , unsigned int addr
, unsigned int *res );

she's a function, she returns an int, she takes three things. no cap. ✨

💜 ARGUMENTS 💜

  • bus — the HD-audio core bus 🚌 like, the main character of this whole operation
  • addr — the codec address 📬 which codec are we even talking to, bestie
  • res — pointer to store the value, NULL when not needed 🫶 so if you don't care about the answer you can literally just pass NULL and move on with your life

🔥 DESCRIPTION 🔥

Returns zero if a value is read, or a negative error code. 💀 that's it. that's the description. short queen.

so real talk: zero = we ate, we got the value. negative = something went sideways, check the error code. simple as. 🌈
