Remarks
Create a local port with CreateLocalPort(String, CFMessagePort+CFMessagePortCallBack, CFAllocator) to receive messages, and create a remote port with CreateRemotePort(CFAllocator, String) to send messages to a named local port.
A local port must be scheduled by calling CreateRunLoopSource() and adding the returned source to a run loop, or by calling SetDispatchQueue(DispatchQueue).
