返回 directory_entry 所指代的全路径。

参数

（无）

返回值

directory_entry 所指代的全路径。

示例

运行此代码

#include <filesystem>#include <fstream>#include <iostream>   namespace fs = std::filesystem;   std::string get_stem(const fs::path& p){return p.stem().string();}void create_file(const fs::path& p){std::ofstream o{p};}   int main(){const fs::path dir{"tmp_dir"}; fs::create_directory(dir); create_file(dir /"one"); create_file(dir /"two"); create_file(dir /"three");   for(constauto& file : fs::directory_iterator(dir)){// 显式转换std::cout<< get_stem(file.path())<<'\n';   // 隐式转换std::cout<< get_stem(file)<<'\n';}   fs::remove_all(dir);}

可能的输出：

two two one one three three
