dwarf_add_AT_ref_address
() creates a
‘reference’ class attribute descriptor containing a relocatable
address value. The created attribute will use DWARF form
DW_FORM_ref_addr
.
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 specifies the attribute code of the created attribute.
Argument pc_value contains a relocatable address which will become the value of the created attribute.
Argument sym_index should specify the ELF symbol index of the symbol to be used when relocating the address value.
If argument err is not NULL, it will be used to store error information in case of an error.
dwarf_add_AT_ref_address
() returns
the created attribute descriptor. In case of an error, function
dwarf_add_AT_ref_address
() returns
DW_DLV_BADADDR
and sets the argument
err.
dwarf_add_AT_ref_address
