这种类型的路径由由反斜杠分隔的组件组成,每个组件最多为GetVolumeInformation函数的lpMaximumComponentLength参数中返回的值, (此值通常为 255 个字符) 。 若要指定扩展长度路径,请使用“\\?\”前缀。 例如,“\\?\D:\long path”。 在Windows 10 版本 1607 及更高版本中启用长路径 从Windows 10 版本 1607 开...
该方法最长可支持32767左右的路径长度。 可以将extended-length path作为路径直接传入open函数来打开文件。但os.path.walk、os.path.join等路径相关的函数在处理extended-length path时会和预期的效果不太一样。建议在代码中始终传递原始路径,自己封装open函数,将filename参数转换为extended-length path并传入真正的open函...
另一方面每个路径名称最大的长度不可以超过255,通过GetVolumeInformation()可以得到lpMaximumComponentLength值(文件名的最大长度)。 通过在路径名称之前添加"\\?\"能够取消路径名称超过MAX_PATH的限制,在C++应该表示为"\\\?\\",Win32 API中给出了创建、打开、读写文件的函数,分别为CreateFile()、WriteFile()、Re...
767 characters. This type of path is composed of components separated by backslashes, each up to the value returned in thelpMaximumComponentLengthparameter of theGetVolumeInformationfunction (this value is commonly 255 characters). To specify

MaximumLength表示Buffer所指向缓冲区的总空间大小,一般等于Buffer被分配时的内存大小,单位为字节 Length表示Buffer所指向缓冲区中字符串的长度,单位也是字节。 注意:Buffer指向的字符串,并不要求以'\0'作为结束。 UNICODE_STRING的常用操作 初始化 RtlInitUnicodeString,这个函数的作用是把一个以'\0'结尾的WCHAR类型的Uni...
