We have the following piece of Ada code. Let us assume that two Bar messages have arrived before we get to the accept clause. During the processing of the accept clause a third Bar message arrives.

How many Bar messages will this task process in total?

task body Foo is
  begin
      -- do some non-message Foo processing here
      accept Bar (parameters) do
        -- do Bar processing here
      end Bar;
      -- do some non-message Foo processing here
  end Foo;
