Question

启动程序时，我想使用current_path（）（“C：\ workspace \ projects”）打印当前路径。然后我希望能够改变路径，让我们说“c：\ program files”，所以当我再次打印current_path（）时，我想要打印“c：\ program files”。像这样的东西

int main()
{
   cout << current_path() << endl;  // c:\workspace\projects
   aFunctionToChangePath("c:\program files");
   cout << current_path() << endl;  // c:\program files
}

库中是否有我失踪的功能，所以我可以实现这个功能吗？

Answer 1

int main()
{
   cout << current_path() << '\n'; // c:\workspace\projects
   current_path("c:\\program files");
   cout << current_path() << '\n';  // c:\program files
}

如果您想对其他目录进行更改，那么我建议您尝试这样做例如：

boost::filesystem::path full_path( boost::filesystem::current_path() );
std::cout << "Current path is : " << full_path << std::endl;
//system("cd ../"); // change to previous dir -- this is NOT working
chdir("../"); // change to previous dir -- this IS working
boost::filesystem::path new_full_path( boost::filesystem::current_path() );
std::cout << "Current path is : " << new_full_path << std::endl;

如何使用Boost.Filesystem更改当前路径
