This call succeeds if the directory exists and the new directory fits inside the dir buffer.
If the call succeeds the dir buffer is filled with the new directory and len contains the
length of the string in the buffer.
For instance if dir contains "C:/Users/MySelf" and rel is "Documents" the buffer will contain
"C:/Users/MySelf/Documents" and len will contain the length of that string. This call can
also be used with rel set to ".." to traverse to parent folders.
