* }
*
* Note that this method behaves like fread() function in C.
* If you need the behavior like read(2) system call,
* This means it retry to invoke read(2) system call to read data with the specified length (or until EOF).
* This behavior is preserved even if <i>ios</i> is non-blocking mode.
* (This method is non-blocking flag insensitive as other methods.)
* If you need the behavior like single read(2) system call,
* consider readpartial, read_nonblock and sysread.
