About This eBook
ePUB is an open, industry-standard format for eBooks. However,
support of ePUB and its many features varies across reading devices and
applications. Use your device or app settings to customize the presentation
to your liking. Settings that you can customize often include font, font
size, single or double column, landscape or portrait mode, and figures that
you can click or tap to enlarge. For additional information about the
settings and features on your reading device or app, visit the device
manufacturer’s Web site.
Many titles include programming code or configuration examples. To
optimize the presentation of these elements, view the eBook in single-
column, landscape mode and adjust the font size to the smallest setting. In
addition to presenting code and configurations in the reflowable text
format, we have included images of the code that mimic the presentation
found in the print book; therefore, where the reflowable format may
compromise the presentation of the code listing, you will see a “Click here
to view code image” link. Click the link to view the print-fidelity code
image. To return to the previous page viewed, click the Back button on
your device or app.
