DWARF_ADD_AT_REFERENCE(3)  Library Functions Manual  DWARF_ADD_AT_REFERENCE(3)

NAME
     dwarf_add_AT_reference -- create and attach an attribute that references
     another DIE

LIBRARY
     DWARF Access Library (libdwarf, -ldwarf)

SYNOPSIS
     #include <libdwarf.h>

     Dwarf_P_Attribute
     dwarf_add_AT_reference(Dwarf_P_Debug dbg, Dwarf_P_Die die,
         Dwarf_Half attr, Dwarf_P_Die ref_die, Dwarf_Error *err);

DESCRIPTION
     Function dwarf_add_AT_reference() creates an attribute descriptor that
     references another debugging information entry in the same compilation
     unit.  The attribute will be of DWARF form DW_FORM_ref4 or DW_FORM_ref8
     depending on the target address size, and will contain the section-
     relative offset of the referenced debugging information entry as its
     value.

     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 ref_die should hold the debugging information entry descriptor
     that the attribute should refer to.

     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_reference() returns the created
     attribute descriptor.  In case of an error, function
     dwarf_add_AT_reference() returns DW_DLV_BADADDR and sets the argument
     err.

ERRORS
     Function dwarf_add_AT_reference() can fail with:

     [DW_DLE_ARGUMENT]       One of the arguments dbg, die or ref_die was
                             NULL.

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