okay bestie, welcome to the Kernel API Manual page for snd_pcm_hw_c...raint_minmax(9) — the title is giving mysterious ellipsis energy, but the NAME section below has the full function name. We're keeping every detail, no cap. 💖

🌸 NAME 🌸

snd_pcm_hw_constraint_minmax — apply a min/max range constraint to an interval.

✨ SYNOPSIS ✨

Here's the signature, copied exactly because we do not mess with code:

int snd_pcm_hw_constraint_minmax (struct snd_pcm_runtime *runtime ,
       snd_pcm_hw_param_t var , unsigned int min , unsigned int max );

🫶 ARGUMENTS 🫶

  • runtime — PCM runtime instance
  • var — hw_params variable to apply the range
  • min — the minimal value
  • max — the maximal value

💅 DESCRIPTION 💅

Apply the min/max range constraint to an interval parameter. That's the whole vibe. 🔥

⭐ RETURN ⭐

Positive if the value is changed, zero if it's not changed, or a negative error code. So: changed = positive, not changed = zero, error = negative. No cap. 🌈
