🌸 NAME 🌸

🎀 LIBRARY 🎀

DWARF Access Library (libdwarf, -ldwarf) — that's the library era, bestie. 🫶

✨ SYNOPSIS ✨

#include <libdwarf.h>

Dwarf_Unsigned
dwarf_add_weakname(Dwarf_P_Debug dbg, Dwarf_P_Die die, char *name,
    Dwarf_Error *err);

---

💫 DESCRIPTION 💫

So, function dwarf_add_weakname() adds information about a weak object to a DWARF producer instance. that's the whole main character move. 👑

• Argument dbg should reference a DWARF producer instance allocated using dwarf_producer_init(3) or dwarf_producer_init_b(3). lowkey important: use one of those init functions, iykyk. 🌈
• Argument die specifies the debugging information entry associated with the weak object. it's giving "this DIE is the moment". 🎀
• Argument name should point to a NUL-terminated string containing the name of the weak object. yes, NUL-terminated, bestie — please don't hand it a random blob. 😭
• If argument err is not NULL, it will be used to store error information in case of an error. so when err is not NULL, error gossip goes there. 🙈

---

⭐ RETURN VALUES ⭐

On success, function dwarf_add_weakname() returns a non-zero value. slay. 💅

In case of an error, function dwarf_add_weakname() returns 0 and sets the argument err. so 0 is giving "something went off", and err gets the tea. 🔥

---

💀 ERRORS 💀

Function dwarf_add_weakname() can fail with:

• [DW_DLE_ARGUMENT] — one of the arguments dbg, die or name was NULL. not the args being missing 😭
• [DW_DLE_MEMORY] — an out of memory condition was encountered during the execution of the function. the memory said nope 💀
