       future Erlang/OTP release.

EXPORTS

       error_message(Format, Args) -> ok

              Types:

                 Format = io:format()
                 Args = [term()]

              Prints error message Args in accordance with Format. Similar to io:format/2.

       flush_receive() -> ok

              Flushes the message buffer of the current process.

       nonl(String1) -> String2

              Types:

                 String1 = String2 = string()

              Removes the last newline character, if any, in String1.

       progname() -> atom()

              Returns the name of the script that started the current Erlang session.

       send(To, Msg) -> Msg

              Types:

                 To = pid() | atom() | {atom(), node()}
                 Msg = term()

              Makes it possible to send a message using the apply/3 BIF.

       sendw(To, Msg) -> term()

              Types:

                 To = pid() | atom() | {atom(), node()}
                 Msg = term()

              As send/2, but waits for an answer. It is implemented as follows:

              sendw(To, Msg) ->
                  To ! {self(),Msg},
                  receive
                      Reply -> Reply
                  end.

              The returned message is not necessarily a reply to the sent message.
