定义于头文件 <filesystem>
enum class file_type {     none = /* unspecified */,     not_found = /* unspecified */,     regular = /* unspecified */,     directory = /* unspecified */,     symlink = /* unspecified */,     block = /* unspecified */,     character = /* unspecified */,     fifo = /* unspecified */,     socket = /* unspecified */,     unknown = /* unspecified */,     /* implementation-defined */ };		(C++17 起)

file_type 定义常量，指示路径所指代的文件或目录的类型。枚举项的值各异。

常量

常量	含义
none	指示文件状态未被求值，或求值时出错
not_found	指示文件未找到（这不被认为是错误）
regular	常规文件
directory	目录
symlink	符号链接
block	阻塞特殊文件
character	字符特殊文件
fifo	FIFO （又称管道）文件
socket	接头文件
实现定义	每个实现支持的附加文件类型的附加实现定义常量
unknown	文件存在但无法确定其类型
