Intro -- introduction to exported driver data

Synopsis

   #include <sys/types.h>
   #include <sys/ddi.h>

Description

This section describes the data definitions (global variables) a developer needs to include in a device driver prior to DDI 8. The kernel accesses these global variables in order to find out information about the driver and its properties.

Usage

The variables defined in this section must have specific names in order for the kernel to be able to find them. See prefix(D1) for a description of the naming convention.

Any private routines and variables defined by a driver or module, except for named entry point routines (see Intro(D2)), should be declared as static.

Global data definitions and named entry point routines are used only in DDI versions prior to version 8.
