snd_ctl_enum_info(9)
π NAME π
okay bestie, this is snd_ctl_enum_info(9) from the Kernel API Manual, and its whole job is literally filling the info structure for an enumerated control. main character energy for a tiny helper, honestly π

πΈ SYNOPSIS πΈ
int snd_ctl_enum_info (struct snd_ctl_elem_info *info , unsigned int channels , unsigned int items , const char *const names[] );
π«Ά ARGUMENTS π«Ά
infoβ the structure to be filled. that's the one getting the glow-up πchannelsβ the number of the control's channels; often one. yes, often just one, and that's valid πitemsβ the number of control values; also the size ofnames. so like, the count does double duty, iykyk πnamesβ an array containing the names of all control values. every value gets a name, no cap π¦
π DESCRIPTION π
Sets all required fields in info to their appropriate values. it's giving "fill in the blanks" but make it kernel-core π
If the control's accessibility is not the default (readable and writable), the caller has to fill info->access. so bestie, if you're doing something non-default, that part is on you β don't forget it, fr fr π
π₯ RETURN π₯
Zero (always successful). like, always. zero and successful, periodt πβ¨
