p The created attribute descriptor will have DWARF form .Dv DW_FORM_addr . If flag .Dv DW_DLC_SIZE_64 is set on the producer instance, the attribute value will be 8 bytes in size. Otherwise the attribute value will be 4 bytes in size.

p Argument .Ar dbg should reference a DWARF producer instance allocated using .Xr dwarf_producer_init 3 or .Xr dwarf_producer_init_b 3 .

p Argument .Ar die should reference a debugging information entry allocated using .Xr dwarf_new_die 3 .

p Argument .Ar attr should specify the attribute code of the created attribute descriptor.

p Argument .Ar pc_value should hold a relocatable address value which will become the value of the created attribute descriptor.

p Argument .Ar sym_index should specify the ELF symbol index of the symbol to be used for relocating the address value.

p If argument .Ar err is not NULL, it will be used to store error information in case of an error.

p Function .Fn dwarf_add_AT_targ_address is deprecated. It is similar to function .Fn dwarf_add_AT_targ_address_b except that it cannot handle all possible symbol index values. .Sh RETURN VALUES On success, these functions return the created attribute descriptor. In case of an error, these functions return .Dv DW_DLV_BADADDR and sets the argument .Ar err . .Sh ERRORS These functions can fail with: l -tag -width ".Bq Er DW_DLE_ARGUMENT" t Bq Er DW_DLE_ARGUMENT Either of the arguments .Ar dbg or .Ar die was NULL. t Bq Er DW_DLE_MEMORY An out of memory condition was encountered during execution. .El .Sh SEE ALSO .Xr dwarf 3 , .Xr dwarf_add_AT_const_value_unsignedint 3 , .Xr dwarf_add_AT_dataref 3 , .Xr dwarf_add_AT_ref_address 3 , .Xr dwarf_add_AT_signed_const 3 , .Xr dwarf_add_AT_unsigned_const 3 , .Xr dwarf_new_die 3 , .Xr dwarf_producer_init 3 , .Xr dwarf_producer_init_b 3
