a unique or well-known bus name or null if connection is not a message bus connection
path of remote object
D-Bus interface to invoke method on
the name of the method to invoke
a #GVariant tuple with parameters for the method or null if not passing parameters
the expected type of the reply, or null
flags from the #GDBusCallFlags enumeration
the timeout in milliseconds, -1 to use the default timeout or G_MAXINT for no timeout
a #GUnixFDList or null
a #GCancellable or null
a #GAsyncReadyCallback to call when the request is satisfied or null if you don't * care about the result of the method invocation
Like gio.dbus_connection.DBusConnection.call but also takes a #GUnixFDList object.
The file descriptors normally correspond to G_VARIANT_TYPE_HANDLE values in the body of the message. For example, if a message contains two file descriptors, fd_list would have length 2, and g_variant_new_handle (0) and g_variant_new_handle (1) would appear somewhere in the body of the message (not necessarily in that order!) to represent the file descriptors at indexes 0 and 1 respectively.
When designing D-Bus APIs that are intended to be interoperable, please note that non-GDBus implementations of D-Bus can usually only access file descriptors if they are referenced in this way by a value of type G_VARIANT_TYPE_HANDLE in the body of the message.
