【MSDN】WSAGetLastError（h_errno）Winsock相关错误代码查询
搬运自MSDN Library - October 2001。找到这页信息的方法是在MSDN打开后的界面找到“索引(N)”选项卡，然后输入关键词“Winsock API ”（注意去掉引号），找到“Error Codes in the API
”，双击打开即可。
如下图所示。
这样就能找到了。当然我会把MSDN上的这些内容搬运到这里的。如果懒得自己打开MSDN看的话请回帖查看我搬运的内容。**** Hidden Message ***** 以下是将h_errno翻译成字符串的函数。配合printf、sprintf、fprintf可以很好地打印错误信息。char*h_error_String()
