pa_simple* pa_simple_new(
        const char *server,

  //流程一：创建共享内存   
  p->context = pa_context_new(pa_threaded_mainloop_get_api(p->mainloop), name);        
  
  //流程二：创建socket
  pa_context_connect(p->context, server, 0, NULL);
  
  //流程三：线程创建
  pa_threaded_mainloop_start(p->mainloop)；
  
  //流程四：填充play Or record参数及注册回调函数
  p->stream = pa_stream_new(p->context, stream_name, ss, map);
  
  //流程五
