Function dwarf_formref() returns the
    compilation unit relative offset of the descriptor referenced by argument
    attr in the location pointed to by argument
    retoffset. Argument attr must be
    a reference that is local to a compilation unit. Permitted forms for
    argument attr are
    DW_FORM_ref1, DW_FORM_ref2,
    DW_FORM_ref4, DW_FORM_ref8
    and DW_FORM_ref_udata.
Function dwarf_global_formref() returns
    the section-relative offset of the descriptor referenced by argument
    attr in the location pointed to by argument
    retoffset. Argument attr should
    be a legal REFERENCE class form. Permitted forms for
    argument attr are:
    DW_FORM_ref_addr,
    DW_FORM_ref_udata,
    DW_FORM_ref1, DW_FORM_ref2,
    DW_FORM_ref4, DW_FORM_ref8
    and DW_FORM_sec_offset. The returned offset is
    relative to the start of the “.debug_info” ELF section.
If argument err is not 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_ERROR and sets
  argument err.
