For a general introduction to device drivers and how to implement them
``Device driver overview''.
If you are particularly interested in understanding
the SVR5 DDI 8 interface,
see the detailed code commentary for a sample DDI 8 driver in
``DDI: 8 sample driver''.
For summary information about a particular feature with cross-references to more detailed information
HDK Technical Reference.
HDK Technical Reference is a set of
free-standing articles on various topics
of interest to driver developers.
The left frame lists the topics alphabetically,
while the right frame groups the articals topically.
Each article gives summary information about the subject
with hotlinks to other places in the documentation set
that provides more details.
You can also use the SEARCH button
under the right frame
to search for information about a specific subject.
Note that the SEARCH capability
is not supported when viewing the documentation
directly from the HDK CD-ROM.

See the appropriate manual pages.
``HDK manual page sections''
provides a full listing of all HDK manual page sections,
with a grid that shows the types of information
that are available for each interface.
The manual pages for each interface are listed
in the right frame when you click on the topic
for that interface type.
When the HDK documentation is installed on your system,
these manual pages can also be accessed
with the man command on SVR5 systems
or the hdkman command on SCO OpenServer 5 systems.
