/**
 * Read data
 *
 * Read should send exactly the number of bytes requested except
 * on EOF or error, otherwise the rest of the data will be
 * substituted with zeroes.  An exception to this is when the file
 * has been opened in 'direct_io' mode, in which case the return
 * value of the read system call will reflect the return value of
 * this operation.
 *
 * fi->fh will contain the value set by the open method, or will
 * be undefined if the open method didn't set any value.
 *
 * Valid replies:
 *   fuse_reply_buf
 *   fuse_reply_iov
 *   fuse_reply_data
 *   fuse_reply_err
 *
 * @param req request handle
 * @param ino the inode number
 * @param size number of bytes to read
 * @param off offset to read from
 * @param fi file information
