The DCB manager is now ready to accept callback postings to the queue
server. Note that this function is normally performed in an ISR of another
service. The DCB manager passes the address of the client callback func-
tion and its associated argument values to the queue server identified by
the handle obtained:

the DMA manager context, this argument is the address of an appropriate

For any reason, flushing the queue of entries for the above callback can be
achieved in one of two ways: by calling the
