Remarks
Declare the type of callback function specified in the pfAppSocketCb parameter of the RegSocketCallbackSc function.When a user calls an asynchronous socket function, the processing request is queued and processed asynchronously. When the requested processing is completed, the callback function is called to return the message data representing the processing result to the user.
The u8Msg parameter of the callback function is passed a message ID that indicates the type of message, and the pvMsg parameter is passed a pointer that points to the message data that stores the processing result.
The type of message data differs depending on the type of message. See each asynchronous socket function for details.
