  *  Note that readpartial behaves similar to sysread.
  *  The differences are:
  *  * If the buffer is not empty, read from the buffer instead of "sysread for buffered IO (IOError)".
- *  * It doesn't cause Errno::EAGAIN and Errno::EINTR.  When readpartial meets EAGAIN and EINTR by read system call, readpartial retry the system call.
+ *  * It doesn't cause Errno::EWOULDBLOCK and Errno::EINTR.  When readpartial meets EWOULDBLOCK and EINTR by read system call, readpartial retry the system call.
  *
  *  The later means that readpartial is nonblocking-flag insensitive.
- *  It blocks on the situation IO#sysread causes Errno::EAGAIN as if the fd is blocking mode.
