Function
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.
On success, function
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.
Function
dwarf_add_AT_ref_address() 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.
