c++ - _stricmp 在字符串匹配时返回错误值。该怎么办？

Question

我有这段代码:

                        second = strtok (NULL,"\n");
                        logprintf(second);
                        if(_stricmp(second,"WINDOWS") == 0)

logprintf 将数据打印到日志文件中，并打印“WINDOWS”(不带引号)。

但是 _stricmp 以某种方式返回 13.. 所以 if 检查永远不会通过。我尝试过使用 sscanf/sprintf/其他字符串方式，但都没有用。我没主意了。

有人可以建议如何解决这个问题吗？

看起来您没有考虑 CRLF 行结尾。以文本模式打开文件会将“\r\n”转换为“\n”，但您的代码中没有任何内容这样做。如果“WINDOWS”后跟“\r\n”，您将其视为“WINDOWS\r”后跟“\n”，因为“\n”是您传递给 strtok。有几种可能的解决方案，但一种是将“\r\n”传递给 strtok。
