Function
dwarf_add_AT_targ_address_b() creates an
attribute descriptor belonging to the ‘address’ class and
attaches it to the debugging information entry referenced by argument
die.
The created attribute descriptor will have DWARF form
DW_FORM_addr
. If flag
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.
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
pc_value should hold a relocatable
address value which will become the value of the created attribute descriptor.
Argument
sym_index should specify the ELF
symbol index of the symbol to be used for relocating the address value.
If argument
err is not NULL, it will be used to
store error information in case of an error.
Function
dwarf_add_AT_targ_address() is deprecated.
It is similar to function
dwarf_add_AT_targ_address_b() except that it
cannot handle all possible symbol index values.
On success, these functions return the created attribute descriptor. In case of
an error, these functions return
DW_DLV_BADADDR
and sets the argument
err.
These functions can fail with:
-
-
- [
DW_DLE_ARGUMENT
]
- Either of the arguments
dbg or
die was NULL.
-
-
- [
DW_DLE_MEMORY
]
- An out of memory condition was encountered during
execution.
