 * @note This function is intrinsically unsafe, in the sense that the
357
 * checked resource may change its existence or permission status from
358
 * one call to another. Thus you should not trust the returned value,
359
 * unless you are sure that no other processes are accessing the
360
 * checked resource.
361
 *
362
 * @note This function is slightly broken until next major bump
363
 *       because of AVIO_RDONLY == 0. Don't use it until then.
