1
Includes the
ioctl.h
include file, which defines common
ioctl
com-
mands. The
ioctl.h
file is located in
/usr/include/sys/ioctl.h
.
2
Includes the
sysconfig.h
header file, which defines the constants that
all device drivers use during configuration. The
sysconfig.h
file is
located in
/usr/include/sys/sysconfig.h
.
3
Includes the
if_ether.h
header file, which defines the
ether_header
data structure. All network drivers typically include this file.
If you are writing the network driver for FDDI media, you also include
the header file
if_fddi.h
. If you are writing the network driver for
Token Ring media, you also include the header file
if_trn.h
.
4
Includes the
devdriver.h
header file, which defines common device
driver data structures and constants. The
devdriver.h
file is located
in
/usr/include/io/common/devdriver.h
.
5
Includes the header file
eisa.h
, which is associated with the ISA bus.
If you are writing the driver to operate on multiple bus architectures,
you must include the bus-specific header file. The
if_el
device driver
is implemented to operate on two buses: the ISA and the PCMCIA.
6
Includes the header files
pcmcia.h
and
cardinfo.h
, which are
associated with the PCMCIA bus.
7
Includes the
lan_common.h
file, which contains definitions that all
local area network (LAN) device drivers need.
8
Includes the device register header file. The directory specification you
make here depends on where you put the device register header file.
