STRUCT LINEDISP_MAP(9)

💖 struct linedisp_map(9) 💖

okay so bestie, welcome to the Kernel API Manual — this little cutie is struct linedisp_map, and it's literally the character mapping</grand>... let me not typo, it's the character mapping struct. it's giving "small but mighty" and we're obsessed 🎀

✨ SYNOPSIS ✨

like, here's the whole vibe, verbatim, no cap:

struct linedisp_map {
    enum linedisp_map_type type;
    union {
      struct seg7_conversion_map seg7;
      struct seg14_conversion_map seg14;
    } map;
    unsigned int size;
 };

that's it. that's the struct. she's compact and she knows it 💅

🌸 Members 🌸

so these are her fields, and yeah, every single one matters:

• type — the type of the character mapping 🦋 like, which flavor of mapping are we even doing here
• map — the conversion character mapping itself 💖 the actual lookup-y goodness
• size — the size of the map 📏 gotta know how big she is

ngl bestie, all three of these are load-bearing. don't skip any of them 🙈
