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
() can fail with:
