voidcreate_hard_link(conststd::filesystem::path&target, constpath&std::filesystem::link); voidcreate_hard_link(conststd::filesystem::path&target, constpath&std::filesystem::link, std::error_code&ec); (C++17 起) 创建硬链接link,将其目标设为target,如同用 POSIXlink():路径名target必须存在...
第一章: 引言在这个数字化迅速发展的时代,软件的每一次迭代和升级都深刻地影响着我们的工作和生活。作为软件工程师,我们经常需要处理文件和目录,而 std::filesystem(C++标准库中的文件系统库)就是在这样的背…
#include <filesystem>namespace fs = std::filesystem;int main() {// 创建一个新目录fs::create_directory("example_dir");// 检查文件是否存在bool file_exists = fs::exists("example_file.txt");// 获取文件大小auto file_size = fs::file_size("example_file.txt");// 更多的文件系统操作......

附带 <filesystem> ,因此无需调查可用性。接下来,选项 1 就足够了,但需要修复: set(CMAKE_CXX_STANDARD 17) # no need to manually adjust the CXXFLAGS add_executable(yourExecutable yourSourceFile.cpp) target_link_libraries(yourExecutable stdc++fs) 这应该会导致使用 -std=c++17 或-std=gnu++17 ...
