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.
