dwarf_hasattr —
#include <libdwarf.h>
int
  
  dwarf_hasattr(Dwarf_Die die,
    Dwarf_Half attr, Dwarf_Bool
    *ret_bool, Dwarf_Error *err);
dwarf_hasattr() tests whether the debugging
  information entry referenced in argument die contains
  the attribute named by argument attr. Legal values for
  argument attr are those denoted by the
  DW_AT_* constants in the DWARF specification.
If the named attribute is present in the debugging information
    entry, function dwarf_hasattr() returns a non-zero
    value in the location pointed to by argument ret_bool.
    If the named attribute is not present, a zero is written instead.
If argument err is not
    NULL, it will be used to return an error descriptor
    in case of an error.
dwarf_hasattr() returns
  DW_DLV_OK. In case of an error, it returns
  DW_DLV_ERROR and sets argument
  err.
dwarf_hasattr() can fail with the following
  error:
