Intro(9S)						    Data Structures for Drivers 						 Intro(9S)

NAME

       Intro, intro - introduction to kernel data structures and properties

DESCRIPTION

       Section	9P  describes kernel properties used by device drivers. Section 9S describes the data structures used by drivers to share informa-
       tion between the driver and the kernel. See Intro(9E) for an overview of device driver interfaces.

       In Section 9S, reference pages contain the following headings:

	   o	  NAME summarizes the purpose of the structure or property.

	   o	  SYNOPSIS lists the include file that defines the structure or property.

	   o	  INTERFACE LEVEL describes any architecture dependencies.

	   o	  DESCRIPTION provides general information about the structure or property.

	   o	  STRUCTURE MEMBERS lists all accessible structure members (for Section 9S).

	   o	  SEE ALSO gives sources for further information.

       Of the preceding headings, Section 9P reference pages contain the NAME, DESCRIPTION, and SEE ALSO fields.

       Every driver MUST include <sys/ddi.h> and <sys/sunddi.h>, in that order, and as final entries.

       The following table summarizes the STREAMS structures described in Section 9S.
