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 memory allocation or deallocation happens.  Client drivers should access
       ivars through the BUS_READ_IVAR(9) interface instead.
