43
44              Types:

51       sendw(To, Msg) -> term()
52
53              Types:
54
55                 To = pid() | atom() | {atom(), node()}
56                 Msg = term()
57
58              As send/2, but waits for an answer. It is  implemented  as  fol‐
59              lows:
60
61              sendw(To, Msg) ->
62                  To ! {self(),Msg},
63                  receive
64                      Reply -> Reply
65                  end.
66
67              The returned message is not necessarily a reply to the sent mes‐
68              sage.
