When generating proxy interfaces, if the flag is set, the DBusMessage 
containing the call with set the NO_REPLY flag. The caller will also not 
block and will return immediately after posting the message.

When generating server (adaptor) interfaces, if the flag is set, it 
imposes a void return type (and no out parameters). 

The glue around the function being called to handle calls will always send 
a reply if the NO_REPLY flag isn't set, and will always not send one if 
the flag is set. That doesn't mean that the functions called don't send 
replies of their own.
