IDirectFBScreen   TestMixerConfiguration

Test mixer configuration.    测试混合器的配置

TestMixerConfiguration (
  IDirectFBScreen   * thiz,
  int   mixer,
  const DFBScreenMixerConfig   * config,
  DFBScreenMixerConfigFlags   * ret_failed
);

If configuration fails and 'ret_failed' is not NULL it will indicate which fields of the configuration caused the error.

如果配置失败和返回ret_failed不为空,那么这就表示配置失败错误的原因.
