34 This module provides a number of annotations which will be useful when
35 dealing with the DBus APIs. There are annotations for switching remote
36 calls between sync, async and no-reply mode. More annotations may be
37 added over time.
38
40 dbus_call_sync
41 Requests that a method call be performed synchronously, waiting for
42 the reply or error return to be received before continuing.
43
44 dbus_call_async
45 Requests that a method call be performed a-synchronously, returning
46 a pending call object, which will collect the reply when it
47 eventually arrives.
48
49 dbus_call_noreply
50 Requests that a method call be performed a-synchronously,
51 discarding any possible reply or error message.
52
53 dbus_call_timeout
54 Indicates that the next parameter for the method call will specify
55 the time to wait for a reply in milliseconds. If omitted, then the
56 default timeout for the object will be used
