3.3 Structures in the Driver’s Allocated Memory
These structures are defined and used by the driver and are part of the context memory allocated
when the driver is opened. These structures are the Module Data Block (MDB), the Device Data
Block (DDB).
Module Data Block: MDB
The MDB is the top-level structure for the module. It contains configuration data about the
module level code and pointers to configuration data about the device level codes.
•
errModule most of the module 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 specified error code back to the application. 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 MDB pointer into a INT4 pointer and retrieve the local error (this
eliminates the need to include the MDB template into the application code).
•
valid indicates that this structure has been properly initialized and may be read by the
USER.
•
stateModule contains the current state of the module and could be set to:
SUNI4x622_MOD_START, SUNI4x622_MOD_IDLE or SUNI4x622_MOD_READY.
