Is there a nice way in the WinAPI to get a path relative to another path? For example:
Have a list of paths relative to:
a\b\c\d
And I'd like to change them all to paths relative to
a\b\c
Is there a neat way to do this or should I get path parsing?

Relevant answer there, but still that does not make this a redundant question. – MSalters Nov 04 '09 at 10:20

As far as i know there is no such functionality in the windows API, but there is e.g. an article on CodeGuru that provides that functionality.
edit:
I stand corrected, there is PathRelativePathTo() in the shell api as mentioned in this answer.

I don't know of any way of doing this directly, but you might be able to do it in a couple of steps using PathCommonPrefix and PathCombine. Otherwise, boost::filesystem may make it possible, eg with the relative_path() method.
