Dwarf_P_Attribute
dwarf_add_AT_targ_address(
Dwarf_P_Debug
dbg,
Dwarf_P_Die die,
Dwarf_Half
attr,
Dwarf_Unsigned pc_value,
Dwarf_Signed sym_index,
Dwarf_Error
*err);
Dwarf_P_Attribute
dwarf_add_AT_targ_address_b(

Dwarf_P_Die die,
Dwarf_Half
attr,
Dwarf_Unsigned pc_value,
Dwarf_Unsigned sym_index,
Dwarf_Error
*err);
DESCRIPTION
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.
RETURN 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.
ERRORS
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.
