ddi_set_driver_private()

dip

data

The ddi_get_driver_private() function returns the address of the device's private data area from the device information structure pointed to by dip.

The ddi_set_driver_private() function sets the address of the device's private data area in the device information structure pointed to by dip with the value of data.

The ddi_get_driver_private() function returns the contents of devi_driver_data. If ddi_set_driver_private() has not been previously called with dip, an unpredictable value is returned.

These functions can be called from user , interrupt, or kernel context.
