📦 version 7.3.1, in nixpkgs unstable

aa_label_snxprint(9) 🎀✨

okay bestie, this one is from the Kernel API Manual, and it's giving "tiny formatting function with main character energy" 💅 We're printing a label name into a string buffer, and honestly? iconic.

💖 NAME 💖

aa_label_snxprint — print a label name to a string buffer. that's the whole vibe, no cap ✨

🌸 SYNOPSIS 🌸

int aa_label_snxprint (char *str , size_t size , struct aa_ns *ns ,
       struct aa_label *label , int flags );

🦋 ARGUMENTS 🦋

  • str — buffer to write to. (MAY BE NULL if size == 0) bestie, read that parenthetical, it's important 👀
  • size — size of buffer. yes ma'am, the number of bytes you're giving it 🧚
  • ns — namespace profile is being viewed from. the lens we're looking through, iykyk 🔍
  • label — label to view (NOT NULL). fr fr, do not pass null here 💀
  • flags — whether to include the mode string. that's it, that's the flag energy 🚩

⭐ RETURN ⭐

size of name written or would be written if larger than available buffer. so the return value is literally the size the name used / would need, no mystery 💫

💜 NOTE 💜

okay so labels do not have to be strictly hierarchical to the ns — as objects may be shared across different namespaces and thus pickup labeling from each ns. If a particular part of the label is not visible it will just be excluded. And if none of the label is visible "---" will be used. iconic fallback behavior, honestly 🫶
