+/**
+ * Create a device file in the local filesystem.
+ * Equivalent of non-portable and possibly obsolete mknod(2).
+ * Whether this makes sense on modern systems is very questionable. But as
+ * libisofs records device files, it should try to restore them where
+ * device creation might be supported.
+ *
+ * @param disk_path
+ *      Path in the local filesystem where to create the file.
+ * @param st_mode
+ *      File type and permission bits as of man stat(2) field st_mode.
+ *      Possibly supported file types are: S_IFCHR , S_IFBLK
+ * @param dev
+ *      System specific parameters for the new device file. It should have
+ *      been originally obtained by a stat(2) call on a system with compatible
+ *      device parameters.
+ * @param os_errno
+ *      Will get filled with errno if a system call fails.
+ *      Else it will be filled with 0.
+ * @param flag
+ *      Bitfield for control purposes.
+ *      bit0= do not issue error messages
+ * @return
+ *      ISO_SUCCESS or <0 to indicate error.
+ *
+ * @since 1.5.8
