NAME

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 headings:

• NAME summarizes the structure's purpose.

• SYNOPSIS lists the include file that defines the structure.

• INTERFACE LEVEL describes any architecture dependencies.

• DESCRIPTION provides general information about the structure.

• STRUCTURE MEMBERS lists all accessible structure members.

• 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
linkblk	DDI/DKI
module_info	DDI/DKI
msgb	DDI/DKI
qband	DDI/DKI
qinit	DDI/DKI
queclass	Solaris DDI
queue	DDI/DKI
streamtab	DDI/DKI
stroptions	DDI/DKI

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.
