在标头<experimental/filesystem>定义 boolexists(file_status s) (1)(文件系统 TS) boolexists(constpath&p); boolexists(constpath&p, error_code&ec) (2)(文件系统 TS) 检查给定文件状态或路径是否对应于某个现存文件或目录。 1)等价于status_known(s)&&s.type()!=file_type::not_found。
1)std::filesystem::exists(status())。 2)std::filesystem::exists(status(ec))。 注意,status()将跟随符号链接到其目标。 参数 返回值 若被指代文件系统对象存在则为true。 异常 若内存分配失败,则任何不标记为noexcept的重载可能抛出std::bad_alloc。

Here, a big file is copied to a temporary path if there is available space: const auto bigFilePath {"bigFileToCopy"}; if (std::filesystem::exists(bigFilePath)) { const auto bigFileSize {std::filesystem::file_size(bigFilePath)}; std::filesystem::path tmpPath {"/tmp"}; if (std...
