DWARF_FORMFLAG(3)

✨ NAME ✨

DWARF_FORMFLAG(3) comes to you from the Library Functions Manual, and the star of the show is dwarf_formflag — the function that returns the value of a BOOLEAN class attribute. No cap, it's a whole vibe 💖.

📚 LIBRARY 📚

The DWARF Access Library (libdwarf, -ldwarf) is the library for this page, bestie. 🫶

🛠️ SYNOPSIS 🛠️

#include <libdwarf.h>

int
dwarf_formflag(Dwarf_Attribute attr, Dwarf_Bool *ret, Dwarf_Error *err);

💅 DESCRIPTION 💅

Okay so here's the tea: dwarf_formflag() writes 1 into the location that argument ret points to when the attribute referenced by argument attr has a non-zero value. If that attribute does not have a non-zero value, it writes 0 instead. Slay. ✨

The form of argument attr must be one of DW_FORM_flag or DW_FORM_flag_present. Those are the forms allowed here — no substitutions, iykyk. 💀

If argument err is not NULL, it will be used to return an error descriptor in case of an error. That's the error-reporting hookup, bestie. 🎀

🌈 RETURN VALUES 🌈

• On success, dwarf_formflag() returns DW_DLV_OK. ✅
• In case of an error, it returns DW_DLV_ERROR and sets argument err. 😭

🚨 ERRORS 🚨

Function dwarf_formflag() may fail with the following errors, bestie — keep an eye out:

• [DW_DLE_ARGUMENT] — either of arguments attr or ret was NULL. 🙈
• [DW_DLE_ATTR_FORM_BAD] — the attribute referenced by argument attr was not of a permitted kind. 💀
