(Dwarf_P_Debug
dbg, Dwarf_P_Die die, Dwarf_Half
attr, Dwarf_P_Die ref_die,
Dwarf_Error *err);
dwarf_add_AT_reference
() creates an attribute
descriptor that references another debugging information entry in the same
compilation unit. The attribute will be of DWARF form
DW_FORM_ref4
or DW_FORM_ref8
depending on the target address size, and will contain the section-relative
offset of the referenced debugging information entry as its value.
Argument dbg should reference a DWARF producer instance allocated using dwarf_producer_init(3) or dwarf_producer_init_b(3).
Argument die should reference a debugging information entry allocated using dwarf_new_die(3).
Argument attr should specify the attribute code of the created attribute descriptor.
Argument ref_die should hold the debugging information entry descriptor that the attribute should refer to.
If argument err is not NULL, it will be used to store error information in case of an error.
dwarf_add_AT_reference
() returns
the created attribute descriptor. In case of an error, function
dwarf_add_AT_reference
() returns
DW_DLV_BADADDR
and sets the argument
err.
dwarf_add_AT_reference
() can fail with:
