Data Structures for Drivers Intro(9S)
NAME
Intro, intro - introduction to kernel data structures
DESCRIPTION
Section 9S describes the data structures used by drivers to
share information between the driver and the kernel.
In this section, reference pages contain the following head-
ings:
o NAME summarizes the structure's purpose.
o SYNOPSIS lists the include file that defines the
structure.
o INTERFACE LEVEL describes any architecture dependen-
cies.
o DESCRIPTION provides general information about the
structure.
o STRUCTURE MEMBERS lists all accessible structure
members.
o SEE ALSO gives sources for further information.
Every driver MUST include <sys/ddi.h> and <sys/sunddi.h>, in
that order, and last.
The following table summarizes the STREAMS structures
described in this section.
Structure Type
copyreq DDI/DKI
copyresp DDI/DKI
datab DDI/DKI
fmodsw Solaris DDI
free_rtn DDI/DKI
iocblk DDI/DKI

The following table summarizes structures that are not
specific to STREAMS I/O.

NOTES
Do not declare arrays of structures as the size of the
structures may change between releases. Rely only on the
structure members listed in this chapter and not on unlisted
members or the position of a member in a structure.
