DWARF_ADD_AT_REF_ADDRESS(3)                           Library Functions Manual

NAME
     dwarf_add_AT_ref_address - create a reference class attribute descriptor

LIBRARY
     DWARF Access Library (libdwarf, -ldwarf)

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.

     [DW_DLE_MEMORY]         An out of memory condition was encountered during
                             execution.
