This function is similar to the @code{readv} function, with the difference
it adds an extra @var{offset} parameter of type @code{off_t} similar to
-@code{pread}. The data is written to the file starting at position
+@code{pread}. The data is read from the file starting at position
@var{offset}. The position of the file descriptor itself is not affected
by the operation. The value is the same as before the call.
