我已经成功地实现的try-catch-ELSE例外，他们不是嵌套。我也希望将消息添加到例外。任何想法，我如何能够做到这一点？

推荐答案

戴夫·汉森已经做了的非常好的包装异常宏为他的优秀著作的一部分的 I2C接口和实现的。你既可以用code批发或借鉴其技术。对于任何人谁做C编程相当数量的，这本书是值得购买＆MDASH;它会改变你改变对C＆NBSP的方式;程序，它会告诉你如何做面向对象的设计以＆nbsp; C。

Dave Hanson has already done a really nice package of exception macros as part of his excellent book C Interfaces and Implementations. You could either use the code wholesale or learn from his techniques. For anyone who does a fair amount of C programming, the book is worth buying—it will change the way you change about C programming, and it will show you how to do object-oriented design in C.
