✨ snd_ctl_new ✨

okay so bestie, buckle up — this is the snd_ctl_new(9) manual page from the Kernel API Manual, and it's genuinely simpler than it looks 💅

🌸 NAME 🌸

snd_ctl_new — create a new control instance with some elements

🎀 SYNOPSIS 🎀

int snd_ctl_new (struct snd_kcontrol **kctl , unsigned int count ,
       unsigned int access , struct snd_ctl_file *file );

🦋 ARGUMENTS 🦋

  • kctl — the pointer where the shiny new control instance gets stored, bestie
  • count — how many elements live inside this control
  • access — the default access flags for the elements in this control
  • file — you pass this one in when you want these elements locked

💖 DESCRIPTION 💖

So what it does: it allocates a memory object for a brand new control instance. That instance gets exactly as many elements as the number you passed in (count). Every single one of those elements gets the access permissions you handed over (access). And when file is given, each element is locked. that's it, that's the whole vibe ✨

🔥 RETURN 🔥

0 on success, or an error code if it doesn't work out 😭
