.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This module provides a number of annotations which will be useful
when dealing with the DBus APIs. There are annotations for switching
remote calls between sync, async and no-reply mode. More annotations
may be added over time.
.SH "METHODS"
.IX Header "METHODS"
.IP "dbus_call_sync" 4
.IX Item "dbus_call_sync"
Requests that a method call be performed synchronously, waiting
for the reply or error return to be received before continuing.
.IP "dbus_call_async" 4
.IX Item "dbus_call_async"
Requests that a method call be performed a\-synchronously, returning
a pending call object, which will collect the reply when it eventually
arrives.
.IP "dbus_call_noreply" 4
.IX Item "dbus_call_noreply"
Requests that a method call be performed a\-synchronously, discarding
any possible reply or error message.
.IP "dbus_call_timeout" 4
.IX Item "dbus_call_timeout"
Indicates that the next parameter for the method call will specify
the time to wait for a reply in milliseconds. If omitted, then the
default timeout for the object will be used
