okay so real talk, this is a page out of the DWARF Access Library — that's libdwarf, and you link it with -ldwarf. Bestie, we're about to find out if a debug entry has kids or not. Family drama, but make it DWARF. 🧚✨

🌸 NAME 🌸

dwarf_get_abbrev_children_flag — returns a flag that tells you whether there are children present 👶🔍

---

🎀 LIBRARY 🎀

DWARF Access Library (libdwarf, -ldwarf)

---

✨ SYNOPSIS ✨

#include <libdwarf.h>

int
dwarf_get_abbrev_children_flag(Dwarf_Abbrev abbrev, Dwarf_Signed *ret,
    Dwarf_Error *err);

---

💖 DESCRIPTION 💖

So dwarf_get_abbrev_children_flag() goes and grabs you a flag. That flag is literally telling you whether the DWARF debug information entry that's attached to a DWARF abbreviation descriptor has any child entries. Like, does this entry have a little family tree or is it an only child? 🌳👑

The abbrev argument? That needs to be a valid DWARF abbreviation descriptor, okay — specifically the kind you get handed back by dwarf_get_abbrev(3). No improvising, use the real one. 🫶

The ret argument needs to point at a spot in memory that's gonna hold the returned flag. And that value is gonna be one of these two icons:

• DW_CHILDREN_yes — the debugging information entry attached to that abbreviation descriptor has children. slay, it's a parent. 👑
• DW_CHILDREN_no — the debugging information entry attached to that abbreviation descriptor has no children. it's giving solo era. 💀

And if the err argument isn't NULL, then it gets used to stash error info whenever something goes wrong. Not NULL = it's doing overtime. 😭

---

🔥 RETURN VALUES 🔥

Function dwarf_get_abbrev_children_flag() returns DW_DLV_OK when it succeeds. 🎉 iconic behavior, no notes.

But if there's an error? It returns DW_DLV_ERROR and sets the err argument. we hate to see it. 🙈

---

⭐ ERRORS ⭐

Function dwarf_get_abbrev_children_flag() can fail with:

• [DW_DLE_ARGUMENT] — either of the arguments abbrev or ret was NULL. yeah, you gotta pass something, bestie. 💀
