Structures Passed through RTOS Buffers
Deferred Processing Vector: DPV
This structure is used in two ways. First, it is used to determine the size of buffer required by the
RTOS for use in the driver. Second, it defines the format of the data that is assembled by the
chipset driver and sent to the application code. It is the application’s responsibility to create one
pool of DPV buffers when the driver calls the user-supplied
Note: the application code is responsible for returning this buffer to the RTOS buffer pool.
sysNbcsDPVBufferRtn can be used to return a buffer to either pool.
The DPR reports events to the application using user-defined callbacks. The DPR uses each
callback to report a functionally related group of events.

Global Variables
Although most of the variables within the driver are not meant to be used by the application code,
there is one global variable that can be of great use to the application code.
This variable is called
(CSMDB). The content of this global variable should be considered read-only by the application.
