NAME
     intro.D1 - introduction to driver data

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

DESCRIPTION
     This section describes the data definitions a developer needs to include
     in a device driver.  The system finds this information in an
     implementation-specific manner, usually tied to the way system
     configuration is handled.

USAGE
     Each driver is uniquely identified by a prefix string specified in its
     configuration file.  The name of all the driver-supplied routines and
     global variables should begin with this prefix.  This will reduce the
     chance of a symbol collision with another driver.  Any private routines
     defined by a driver that are not entry point routines should be declared
     as static.  Also, any global variables that are private to the driver
     should be declared as static.
