 .Fc
 .Sh DESCRIPTION
 Function
 .Fn dwarf_get_arange_info
 extracts address range information from a
 .Vt Dwarf_Arange
 descriptor.
 .Pp
 Argument
 .Ar ar
 should reference a valid
 .Vt Dwarf_Arange
 descriptor returned by function
 .Xr dwarf_get_aranges 3 .
 .Pp
 Argument
 .Ar start
 should point to a location which will hold the start value of the
 address range associated with the descriptor.
 .Pp
 Argument
 .Ar length
 should point to a location which will hold the length in bytes of the
 address range associated with the descriptor.
 .Pp
 Argument
 .Ar cu_die_offset
 should point to a location which will be set to an offset, relative to
 the
 .Dq ".debug_info"
 section, of the first debugging information entry in the compilation
 unit associated with argument
 .Ar ar .
 .Pp
 If argument
 .Ar err
 is not NULL, it will be used to store error information in case of an
 error.
 .Sh RETURN VALUES
 Function
 .Fn dwarf_get_arange_info
 returns
 .Dv DW_DLV_OK
 when it succeeds.
 In case of an error, it returns
 .Dv DW_DLV_ERROR
 and sets the argument
 .Ar err .
 .Sh ERRORS
 Function
 .Fn dwarf_get_arange_info
 can fail with:
 .Bl -tag -width ".Bq Er DW_DLE_ARGUMENT"
 .It Bq Er DW_DLE_ARGUMENT
 One of the arguments
 .Ar ar ,
 .Ar start ,
 .Ar length
 or
 .Ar cu_die_offset
 was NULL.

 .Sh EXAMPLE
 To loop through all the address lookup table entries, use:
 .Bd -literal -offset indent
 Dwarf_Debug dbg;
 Dwarf_Addr start;
 Dwarf_Arange *aranges;
 Dwarf_Off die_off;
 Dwarf_Signed i, cnt;
 Dwarf_Unsigned length;
 Dwarf_Error de;

 	    &die_off, &de) != DW_DLV_OK) {
 		warnx("dwarf_get_arange_info: %s",
 		    dwarf_errmsg(de));
 		continue;
