snd_soc_add_dai_controls(9)
πΈ NAME πΈ
snd_soc_add_dai_controls β bestie, this one adds an array of controls to a DAI. It's literally the convenience function for adding a whole list of controls at once, so you don't have to do it one by one like some kind of pre-2010 gremlin π
β¨ SYNOPSIS β¨
int snd_soc_add_dai_controls (struct snd_soc_dai *dai , const struct
struct snd_kcontrol_new *controls , int num_controls );
okay so the actual signature in the manpage is:
int snd_soc_add_dai_controls (struct snd_soc_dai *dai , const struct
snd_kcontrol_new *controls , int num_controls );
three args, one return value, zero drama π«Ά
π ARGUMENTS π
daiβ the DAI you're adding controls to. this is the main character of the operation πcontrolsβ the array of controls you want to add. yes, an array, plural, we're doing this in bulk bestie π¦num_controlsβ how many elements are actually in that array. important!! you gotta tell it how many, it's not gonna count them for you π
π DESCRIPTION π
So the vibe here is simple: it returns 0 for success, and anything else means error. That's it. That's the whole description. No cap π₯
lowkey love a function whose whole documented behaviour is "returns 0 or it doesn't" β iconic, unbothered, minimal π
