DEVICE_GET_IVARS(9) BSD Kernel Developer's Manual DEVICE_GET_IVARS(9)
NAME
device_get_ivars, device_set_ivars -- access bus private variables
SYNOPSIS
#include <sys/param.h>
#include <sys/bus.h>
void *
device_get_ivars(device_t dev);
void
device_set_ivars(device_t dev, void *ivar);
DESCRIPTION
The device_get_ivars() function returns the bus-specific instance variables of a device.
The device_set_ivars() function sets the bus-specific instance variables of a device.
Typically, only bus drivers will use these functions. The kernel assumes that the bus driver will manage this memory, and no automatic mem-
ory allocation or deallocation happens. Client drivers should access ivars through the BUS_READ_IVAR(9) interface instead.
