//enumdefinition state of one error
EnumState:
(
ERROR_STATE_NULL, //default
ERROR_STATE_C, //comming,
ERROR_STATE_CG, //comming,gone
ERROR_STATE_CA, //comming,acknowledge
ERROR_STATE_CGA //comming,gone,acknowledge
);
这些错误状态如何理解哈？比如说ERROR_STATE_C, //comming,是不是指错误发生?
ERROR_STATE_CG, //comming,gone指错误发生，而且错误已经消失?
ERROR_STATE_CA, //comming,acknowledge错误发生，且被确认？
对程序编程有什么作用，怎么用哈？谢谢指点。
