+ * * :noreuse - The data will only be accessed once.
+ *
+ * The semantics of a piece of advice are platform-dependent. See
+ * <em>man 2 posix_fadvise</em> for details.
+ *
+ * "data" means the region of the current file that begins at
+ * _offset_ and extends for _len_ bytes. If _len_ is 0, the region
+ * ends at the last byte of the file. By default, both _offset_ and
+ * _len_ are 0, meaning that the advice applies to the entire file.
+ *
+ * If an error occurs, one of the following exceptions will be raised:
+ *
+ * * <code>IOError</code> - The <code>IO</code> stream is closed.
+ * * <code>Errno::EBADF</code> - The file descriptor of the current file is
+ invalid.
+ * * <code>Errno::EINVAL</code> - An invalid value for _advice_ was given.
+ * * <code>Errno::ESPIPE</code> - The file descriptor of the current
+ * * file refers to a FIFO or pipe. (Linux raises <code>Errno::EINVAL</code>
+ * * in this case).
+ * * <code>TypeError</code> - Either _advice_ was not a Symbol, or one of the
+ other arguments was not an <code>Integer</code>.
+ * * <code>RangeError</code> - One of the arguments given was too big/small.
+ *
+ * This list is not exhaustive; other Errno:: exceptions are also possible.
