Lets make MojoCreateMessagePipeResult a real object

[alokp, 2016/10/25 05:01:37]

Sorry for my ignorance. By real object, do you mean an interface with read-only
attributes? Is that more efficient, since I do not need any member function?

+    MojoResult writeMessage(MojoHandle pipe, BufferSource buffer, sequence<MojoHandle> handles, MojoWriteMessageFlags flags);
+    MojoReadMessageResult readMessage(MojoHandle pipe, MojoReadMessageFlags flags);
+};
