dwarf_formref(Dwarf_Attribute attr, Dwarf_Off *retoffset, Dwarf_Error *err);
int
dwarf_global_formref(Dwarf_Attribute attr, Dwarf_Off *retoffset, Dwarf_Error *err);
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.
