die_get_typename_from_type(9)

okay so bestie, we're opening the Kernel API Manual for die_get_typename_from_type(9) — yes, the name is giving "why are there so many underscores," but we're gonna understand it and slay ✨💅

🌸 NAME 🌸

die_get_typename_from_type — Get the name of given type DIE 🎀

✨ SYNOPSIS ✨

int die_get_typename_from_type (Dwarf_Die *type_die , struct strbuf *buf
       );

🫶 ARGUMENTS 🫶

• type_die — a type DIE 🌈
• buf — a strbuf for result type name 🍓

💖 DESCRIPTION 💖

okay so here's the tea: it gets the name of type_die and stores it in buf 👑 Return 0 if succeeded, and return -ENOENT if failed to find type name. That's the whole mood.

Note that the result will store the typedef name if possible — and if the type is a function pointer, it stores "*(function_type)" 💀✨
