工作后比较忙,没大块的时间来酝酿博客的写作,所以随时记点笔记,一来方便自己查阅,二来也督促自己学习和总结。如果能对大家有所帮助,就更加开心了。
提取出路径的公共前缀是个比较实用的功能,函数原型如下:
int PathCommonPrefix( LPCTSTR pszFile1, LPCTSTR pszFile2, LPTSTR pszPath);
各个参数解释如下(这英语相当简单~):
-
pszFile1
- [in] A pointer to a null-terminated string of maximum length MAX_PATH that contains the first path name. pszFile2
- [in] A pointer to a null-terminated string of maximum length MAX_PATH that contains the second path name. pszPath
-
[out] A pointer to a buffer that receives the common prefix. This buffer is assumed to be at least MAX_PATH characters in size. If there is no common prefix, it will be set to NULL.
下面给出示范:

运行结果如图所示:
本篇《【MoreWindows工作笔记6】PathCommonPrefix 路径的公共前缀》介绍了使用函数提取路径的公共前缀,并使用公共前缀来判断路径的包含关系,下一篇《【MoreWindows工作笔记7】PathIsPrefix 判断路径的包含关系》将介绍一个更简单的API函数来判断路径的包含关系——PathIsPrefix。欢迎继续浏览~
