💖 DWARF_FIND_MACRO_VALUE_START(3) — return the address of the first byte of a macro value 💖

okay bestie, welcome to the Library Functions Manual. Tiny header tea: the top line spells the title DWARF_FIND_MACRO_VALUE_S(3) (yes, _S, not _START) — typo princess behavior — but the function you actually call is dwarf_find_macro_value_start(). 💅

🌸 NAME 🌸

dwarf_find_macro_value_start — return the address of the first byte of a macro value

🎀 LIBRARY 🎀

This page is chillin’ in the DWARF Access Library — that’s libdwarf, and you link it with -ldwarf. 🫶

✨ SYNOPSIS ✨

#include <libdwarf.h>

char *
dwarf_find_macro_value_start(char *macro_string);

💅 DESCRIPTION 💅

Given a DWARF macro string, function dwarf_find_macro_value_start() returns a pointer to the first byte of the macro value part of the macro string. That’s the whole quest, bestie. ✨

Argument macro_string should be a NUL-terminated string conforming to the macro format defined in the DWARF standard; see dwarf(4). 🦋

🔥 RETURN VALUES 🔥

  • On success — function dwarf_find_macro_value_start() returns a pointer to the first byte of the macro value. slay. 💖
  • If the macro value part was not found — function dwarf_find_macro_value_start() returns a pointer to the NUL-byte terminating argument macro_string. read that twice, bestie. 👀
  • If argument macro_string was NULL — function dwarf_find_macro_value_start() returns NULL. literally NULL. 💀
