/* This program demonstrates how to translate an external link created on
* a Windows machine into a format that a *nix machine can read.
* This is done by registering a new traversal function for external links.
*
* This example is designed to be run on Unix and will create an external
* link with a Windows-style path. Using the traversal function below,
* the example then successfully follows the external link.
*
* The external link will create a file called "u2w/u2w_target.h5".
* The example will fail if the directory u2w does not exist.

/* "Windows to Unix" traversal function for external links
*
* Translates a filename stored in Unix format to Windows format by replacing
* forward slashes with backslashes.
* Makes no attempt to handle Windows drive names (e.g., "C:\"), spaces within
* file names, quotes, etc. These are left as an exercise for the user. :)
* Note that this may not be necessary on your system; many Windows systems can
* understand Unix paths.
