dwarf_hasform() indicates whether the DWARF
  attribute denoted by argument attr has the attribute
  form specified by argument form. If the attribute has
  the specified form, then argument ret is set to a
  non-zero value, otherwise it is set to zero. If argument
  err is non-NULL, it will be used to return an error
  descriptor in case of an error.
Function dwarf_whatform() sets the
    location specified by argument retform to the
    attribute form code for the DWARF attribute referenced by argument
    attr. If the attribute referenced by argument
    attr has an indirect form attribute, this function
    will return the final form for the attribute. If argument
    err is non-NULL, it will be used to return an error
    descriptor in case of an error.
Function dwarf_whatform_direct() sets the
    location specified by argument retform to the
    attribute form code for the DWARF attribute referenced by argument
    attr. If the form is an indirect form, the function
    sets the location specified by argument retform to
    DW_FORM_indirect. If argument
    err is non-NULL, it will be used to return an error
    descriptor in case of an error.
DW_DLV_OK on success. In case of
  an error, these functions return DW_DLV_ERR and set
  argument err.
