+ * This is a template implementation of the "__lseek" function used by

+ * implementation.
+ *
+ * The "__lseek" function makes the next file operation (__read or
+ * __write) act on a new location.  The parameter "whence" specifies
+ * how the "offset" parameter should be interpreted according to the
+ * following table:
+ *
+ *  0 (=SEEK_SET) - Goto location "offset".
+ *  1 (=SEEK_CUR) - Go "offset" bytes from the current location.
+ *  2 (=SEEK_END) - Go to "offset" bytes from the end.
+ *
+ * This function should return the current file position, or -1 on
+ * failure.
