我用 Mingw-w64 64bit 编译的，报了一个warning 和一些错误 导致 编译失败，编译报错好像是没有连接 wsock 库。
那个 warning 需要处理吗？谢谢！

您好，韦老师，请教点用 c 设计的问题。您在知乎上谈过 c 的思维，是自底向上的，逐步迭代的，强调可拆分性和简单性，这也成为了我学习设计的指导方法。

我也拜读了您的网络库，我发现我太不喜欢您那样 abcd.h:abcd.c = 1:1 的形式，因为这样给用户的 .h 会暴露太多信息。我更喜欢 libevent2 那么，分为内部使用 abcd-internal 和提供给外部使用的 include/abcd.h 。但是这样无疑让代码文件变多，也没有原来那么直观, 你认为这样是否是画蛇添足？或者说您觉得 libevent2 的设计怎么样？

很想听听您的建议...
