int
  
  dwarf_formflag(Dwarf_Attribute
    attr, Dwarf_Bool *ret,
    Dwarf_Error *err);
dwarf_formflag() sets the location pointed to
  by argument ret to 1 if the attribute referenced by
  argument attr has a non-zero value, or 0 otherwise. The
  form of argument attr must be one of
  DW_FORM_flag or
  DW_FORM_flag_present.
If argument err is not
    NULL, it will be used to return an error descriptor
    in case of an error.
dwarf_formflag() returns
  DW_DLV_OK on success. In case of an error, it returns
  DW_DLV_ERROR and sets argument
  err.
dwarf_formflag() may fail with the following
  errors:
