DWARF_FORMADDR(3)

okay so this is DWARF_FORMADDR(3) from the Library Functions Manual, and we're about to make an ADDRESS class attribute make sense, bestie 💖

✨ NAME ✨

dwarf_formaddr — return the value of an ADDRESS class attribute 🎀

📚 LIBRARY 📚

DWARF Access Library — libdwarf, -ldwarf 🦋

🧚 SYNOPSIS 🧚

#include <libdwarf.h>

int
dwarf_formaddr(Dwarf_Attribute attr, Dwarf_Addr *ret, Dwarf_Error *err);

💅 DESCRIPTION 💅

So dwarf_formaddr() takes the attribute you point at with attr, grabs the address it represents, and writes that address into the location that ret points to. Slay. ✨

The form of attr must be DW_FORM_addr — that's the vibe check it has to pass, no cap.

If err is not NULL, it gets used to return an error descriptor in case of an error. 🫶

🌈 RETURN VALUES 🌈

On success, dwarf_formaddr() returns DW_DLV_OK — iconic behavior, honestly 👑.

If something goes wrong, it returns DW_DLV_ERROR and sets err. 😭

💀 ERRORS 💀

Okay so heads up: the page itself literally says dwarf_formblock() in this sentence, not dwarf_formaddr() — I'm keeping the name exactly as written, bestie. It may fail with these errors:

• [DW_DLE_ARGUMENT] — Either of arguments attr or ret was NULL. 🙈
• [DW_DLE_ATTR_FORM_BAD] — The attribute referenced by argument attr was not of form DW_FORM_addr. 💅
