Device Data Block: DDB

The DDB is the top-level structure for each device. It contains configuration data about the device level code and pointers to configuration data about device level sub-blocks.

•errDevice most of the device API functions return a specific error code directly. When the returned code is SUNI4x622_FAILURE, this indicates that the top-level function was not able to carry the specific error code back top the application. In addition, some device functions do not return an error code. Under those circumstances, the proper error code is recorded in this element. The element is the first in the structure so that the USER can cast the DDB pointer to a INT4 pointer and retrieve the local error (this eliminates the need to include the DDB template in the application code).

•valid indicates that this structure has been properly initialized and may be read by the USER.

•stateDevice contains the current state of the device and could be set to:

SUNI4x622_START, SUNI4x622_PRESENT, SUNI4x622_ACTIVE or

SUNI4x622_INACTIVE.

•usrCtxt is a value that can be used by the USER to identify the device during the execution of the callback functions. It is passed to the driver when suni4x622Add is called and returned to the USER in the DPV when a callback function is invoked. The element is unused by the driver itself and may contain any value.
