ORDERING driver specific cntls.

|
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Set offset for the next IO operation. This is not allowed when there is an outstanding IO operation. This operation clears all the buffered data.

|
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Set the maximum number of reads that ordering driver can have outstanding on driver(s) below.

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. This driver can be used in 2 modes; ordering (care about offsets of the data read - underlying transport driver may deliver data out of order - this driver will rearrange data based on the offset and deliver inorder to user) and buffering (do not care about offsets - just buffer the data read abd deliver it when requested). This attribute control can be used to enable buffering.

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Set the size of the buffer that ordering driver creates to use for reading data from the driver below it.

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Get the size of the buffer used for the internal reads.
