问题 How can I use the Boost library to change the permissions of a file to read-only? There are some questions that I have already seen, such as this and this, but I still don't know how to do it, I have tried doing boost::filesystem::wpath path = L"abc.txt"; if( boost::filesystem::exists( path ) && boost::filesystem::is_regular_file( path ) ) { boost::filesystem::file_status s = boost::filesystem::status( path ); /* here I need to set file permissitons to READ ONLY for `path` file */ } Any ideas
