SYNOPSIS
#include <libdwarf.h>
Dwarf_P_Attribute
dwarf_add_AT_ref_address(
Dwarf_P_Debug
dbg,
Dwarf_P_Die die,
Dwarf_Half
attr,
Dwarf_Unsigned pc_value,
Dwarf_Unsigned sym_index,
Dwarf_Error
*err);
DESCRIPTION
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.
RETURN VALUES
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.
ERRORS
Function
dwarf_add_AT_ref_address() can fail with:
-
-
- [
DW_DLE_ARGUMENT
]
- Either of the arguments dbg or
die was NULL.
