Getting a directory name from a filename

Question

I have a filename (C:\folder\foo.txt) and I need to retrieve the folder name (C:\folder) in unmanaged C++. In C# I would do something like this:

string folder = new FileInfo("C:\folder\foo.txt").DirectoryName; 

Is there a function that can be used in unmanaged C++ to extract the path from the filename?

Using Boost.Filesystem:

boost::filesystem::path p("C:\\folder\\foo.txt"); boost::filesystem::path dir = p.parent_path();
