Synchronously invokes the
method_name method on this.
method_name contains any dots, then
name is split into interface and method name parts. This allows using
this for invoking methods on other interfaces.
If the DBusConnection associated with this is
disconnected then the operation will fail with g_io_error_closed. If
cancellable is canceled, the
operation will fail with g_io_error_cancelled. If
parameters contains a value not compatible
with the D-Bus protocol, the operation fails with g_io_error_invalid_argument.
The calling thread is blocked until a reply is received. See call for the asynchronous version of this method.
If this has an expected interface (see
method_name is referenced by it,
then the return value is checked against the return type.
