NAME
drv_majors - target driver's device numbering structure
SYNOPSIS
#include <sys/sdi_edt.h>
#include <sys/ddi.h>
DESCRIPTION
The drv_majors structure is used to specify the device nodes
for a specific device. This structure is part of the owner
structure; its fields must be initialized by the target
driver's rinit routine. The drv_majors structure must not be
allocated directly by a driver.
b_maj the block major number of the target driver for this
device.
c_maj the character major number of the target driver for this
device.
minors_per
the number of minor numbers reserved for this device.
first_minor
the first minor number for this device
Structure Members
The drv_majors structure, defined as struct drv_majors,
contains the following structure members:
major_t b_maj; /* block major number */
major_t c_maj; /* character major number */
ulong_t minors_per; /* number of minors per device instance */
minor_t first_minor; /* the first minor for this device */
