DWARF_GET_ADDRESS_SIZE(3)

✨ DWARF_GET_ADDRESS_SIZE 💅

okay bestie, so this one lives in the DWARF Access Library (that's libdwarf, and you link it with -ldwarf 🎀). It's a tiny little function but it's literally doing the most important thing: telling you how many bytes an address takes up. icon behavior, no cap.

---

🌸 SYNOPSIS 🌸

#include <libdwarf.h>

int
dwarf_get_address_size(Dwarf_Debug dbg, Dwarf_Half *addr_size,
    Dwarf_Error *err);

---

💖 DESCRIPTION 💖

okay so dwarf_get_address_size() returns the size in bytes of a native address for a program object. that's it, that's the whole vibe. ✨

• dbg — this should denote a DWARF debug context that you created from a program object using dwarf_init(3). main character argument fr.
• addr_size — point this at a location that will hold the returned size. like, give it somewhere to live 🫶
• err — if it's non-NULL, it gets used to return error information. if you pass NULL, that's your choice bestie 💀

---

🦋 RETURN VALUES 🦋

On success, function dwarf_tag() returns DW_DLV_OK 👑 (yes, the manpage really does say dwarf_tag() here — i'm not fixing it, i'm just reporting it, iykyk 🙈).

In case of an error, it returns DW_DLV_ERROR and sets argument err. sad girl hours 😭

---

🔥 ERRORS 🔥

Function dwarf_get_address_size() can fail with the following error:

• [DW_DLE_ARGUMENT] — either of arguments dbg or addr_size was NULL. so like... actually pass them, bestie 💅
