DWARF_ADD_AT_TARG_ADDRESS(3) FreeBSD Library Functions Manual
NAME
dwarf_add_AT_targ_address, dwarf_add_AT_targ_address_b - create and
attach address class attributes
LIBRARY
DWARF Access Library (libdwarf, -ldwarf)
SYNOPSIS
#include <libdwarf.h>
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_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_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.
