43.Sh DESCRIPTION
44Function
45.Fn dwarf_lne_end_sequence
46sets the address that indicates the end of a sequence of target machine
47instructions.
48.Pp
49Argument
50.Ar dbg
51should reference a DWARF producer instance allocated using
52.Xr dwarf_producer_init 3
53or
54.Xr dwarf_producer_init_b 3 .
55.Pp
56Argument
57.Ar addr
58specifies an address value which is the first byte after the end of a
59instruction sequence.
60.Pp
61If argument
62.Ar err
63is not NULL, it will be used to store error information in case
64of an error.
65.Sh RETURN VALUES
66On success, function
67.Fn dwarf_lne_end_sequence
68returns
69.Dv DW_DLV_OK .
70In case of an error, function
71.Fn dwarf_lne_end_sequence
72returns
73.Dv DW_DLV_NOCOUNT
74and sets the argument
75.Ar err .
76.Sh ERRORS
77Function
