DWARF_WHATATTR(3)

💅 DWARF_WHATATTR 💅

okay so bestie, this is a page from the DWARF Access Library man pages — that's libdwarf, and you link it with -ldwarf. she's giving very much "small function, big purpose" and honestly? iconic. ✨

🌸 NAME 🌸

dwarf_whatattr — retrieves the attribute code for a DWARF attribute. that's it. that's her whole job. and she does it flawlessly. 💅

🦋 LIBRARY 🦋

DWARF Access Library (libdwarf, -ldwarf). add that flag or she won't show up, no cap.

🎀 SYNOPSIS 🎀

#include <libdwarf.h>

int
dwarf_whatattr(Dwarf_Attribute attr, Dwarf_Half *retcode,
    Dwarf_Error *err);

✨ DESCRIPTION ✨

okay so picture this: you've got a DWARF attribute chillin' in attr, right? and you're like "girl, what are you? what's your attribute code?" 🫶

that's the whole vibe here. dwarf_whatattr() retrieves the attribute code for the DWARF attribute referenced by argument attr, and writes it out to the location pointed to by argument retcode. like she literally hands you the answer. queen behavior. 👑

and if argument err is not NULL, it will be used to return an error descriptor in case of an error. so you get a little note back if things go sideways. thoughtful. 🧚

🔥 RETURN VALUES 🔥

• on success, dwarf_whatattr() returns DW_DLV_OK — slay, everything worked, we love to see it 💖
• in case of an error, it returns DW_DLV_ERROR and sets argument err — so like, it's not gonna leave you guessing. she tells you. 😭

💀 ERRORS 💀

here's the one and only way dwarf_whatattr() can fail, and it's lowkey a vibe check on your pointers:

• [DW_DLE_ARGUMENT] — either of argument attr or retcode was NULL. yeah. you passed her nothing. she can't work with nothing, bestie. 🙈
