   .Sh DESCRIPTION
   These functions retrieve the offsets, relative to the
   .Dq ".debug_info"
   DWARF section, of the debugging information entries describing the
   compilation unit associated with a
   .Vt Dwarf_Arange
   descriptor.
   .Pp
   Function
   .Fn dwarf_get_arange_cu_header_offset
   retrieves the offset of the compilation unit header associated with
   argument
   .Ar ar ,
   and stores it in the location pointed to by argument
   .Ar ret .
   .Pp
   Function
   .Fn dwarf_get_cu_die_offset
   retrieves the offset of the debugging information entry for the
   compilation unit associated with argument
   .Ar ar ,
   and stores it in the location pointed to by argument
   .Ar ret .
   .Pp
   If argument
   .Ar err
   is not NULL, these functions will use it to store error information,
   in case of an error.
   .Sh RETURN VALUES
   On success, these functions returns
   .Dv DW_DLV_OK .
   In case of an error, they return
   .Dv DW_DLV_ERROR
   and set the argument
   .Ar err .
   .Sh ERRORS
   These functions may fail with:
   .Bl -tag -width ".Bq Er DW_DLE_ARGUMENT"
   .It Bq Er DW_DLE_ARGUMENT
   Argument
   .Ar ar
   was not a valid
   .Vt Dwarf_Arange
   descriptor.
   .It Bq Er DW_DLE_ARGUMENT
   Argument
   .Ar ret
   was NULL.
