+ * Function:    test_path_env
+ *
+ * Purpose:     Test whether the value of HDF5_EXTFILE_PREFIX will overwrite
+ *              the efile_prefix dataset access property.
+ *              This will create an HDF5 file in a subdirectory which will
+ *              refer to ../extern_*a.raw
+ *              The files are then accessed by setting the HDF5_EXTFILE_PREFIX
+ *              environment variable to "${ORIGIN}".
+ *              The efile_prefix dataset access property is set to "someprefix",
+ *              which will cause an error if the value is not overwritten by
+ *              the environment variable.
+ *
+ * Return:      Success:    0
+ *              Failure:    1
