💖 DWARF_ADD_AT_FLAG(3) 💖

okay bestie, welcome to libdwarf, aka the DWARF Access Library (that's libdwarf, linked with -ldwarf) 🧚 and today's main character is dwarf_add_AT_flag() — she creates a flag attribute and attaches it to a debugging information entry. periodt. 💅

✨ NAME ✨

dwarf_add_AT_flag — create and attach a flag attribute 🎀

🦋 LIBRARY 🦋

DWARF Access Library (libdwarf, -ldwarf) 💜

🌸 SYNOPSIS 🌸

#include <libdwarf.h>

Dwarf_P_Attribute
dwarf_add_AT_flag(Dwarf_P_Debug dbg, Dwarf_P_Die die, Dwarf_Half attr,
    Dwarf_Small flag, Dwarf_Error *err);

💫 DESCRIPTION 💫

so dwarf_add_AT_flag() literally creates an attribute descriptor that belongs to the ‘flag’ class, and attaches it to the debugging information entry referenced by argument die. the created attribute descriptor will have DWARF form DW_FORM_flag. no cap. 🔥

• argument dbg should reference a DWARF producer instance allocated using dwarf_producer_init(3) or dwarf_producer_init_b(3) 🫶
• argument die should reference a debugging information entry allocated using dwarf_new_die(3) ✨
• argument attr should specify the attribute code for the new attribute descriptor 👑
• argument flag should specify the value of the new attribute descriptor. a zero value is treated as ‘false’ and a non-zero value as ‘true’. iykyk 😌
• if argument err is not NULL, it will be used to store error information in case of an error 💀

⭐ RETURN VALUES ⭐

on success, function dwarf_add_AT_flag() returns the created attribute descriptor. slay. 💅 in case of an error, function dwarf_add_AT_flag() returns DW_DLV_BADADDR and sets the argument err. 😭

🌈 ERRORS 🌈

function dwarf_add_AT_flag() can fail with:

• [DW_DLE_ARGUMENT] — either of the arguments dbg or die was NULL. 🙈
• [DW_DLE_MEMORY] — an out of memory condition was encountered during the execution of the function. 💀
