✨ NAME ✨

cipso_v4_map_cat_enum_valid — checks to see if the categories are valid. This is the cipso_v4_map_cat_enum_valid(9) page from the Kernel API Manual, and bestie, it’s giving “category vibe check” energy. 💅

🌸 SYNOPSIS 🌸

int cipso_v4_map_cat_enum_valid (const struct cipso_v4_doi *doi_def ,
const unsigned char *enumcat , u32 enumcat_len );

🎀 ARGUMENTS 🎀

  • doi_def — the DOI definition 💖
  • enumcat — category list ✨
  • enumcat_len — length of the category list in bytes 🎀

💅 DESCRIPTION 💅

Okay so this one checks the given categories against the given DOI definition. It returns a negative value if any of the categories do not have a valid mapping, and a zero value if all of the categories are valid. No cap, that’s the whole plot. 🫶
