snd_ctl_enum_info(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸŽ€ NAME πŸŽ€

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 πŸ’…βœ¨


🌸 SYNOPSIS 🌸

int snd_ctl_enum_info (struct snd_ctl_elem_info *info , unsigned int channels , unsigned int items , const char *const names[] );

🫢 ARGUMENTS 🫢

  • info β€” the structure to be filled. that's the one getting the glow-up πŸ’–
  • channels β€” the number of the control's channels; often one. yes, often just one, and that's valid πŸŽ€
  • items β€” the number of control values; also the size of names. so like, the count does double duty, iykyk 🌟
  • names β€” an array containing the names of all control values. every value gets a name, no cap πŸ¦‹

πŸ’… DESCRIPTION πŸ’…

Sets all required fields in info to their appropriate values. it's giving "fill in the blanks" but make it kernel-core 🌈

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 😭


πŸ”₯ RETURN πŸ”₯

Zero (always successful). like, always. zero and successful, periodt πŸ‘‘βœ¨
