+Subject: [PATCH] src/adapter.c : Event callback registration optimization    
+ After read info complete,too many event registration functions are not
+ conducive to subsequent expansion.     If we want to add a new event,
+ according to the previous logic, we must add an event registration function,
+ the code is too redundant.     Therefore, I added a global time callback
+ registration in this submission.     If you want to add event registration
+ later, you only need to add the new event and event callback function to the
+ global table.
