Note that this header is repeated at each sub-buffer.
Data Size? 4 ???
Data size is the size, in bytes, of data present in the sub-buffer.
Events Lost ? 4 Number of lost events
This is a free-running 32-bit counter. So you can know how many events
were lost between two sub-buffers headers.
Subbuffer Corrupt ? 4
Free running 32-bit counter. Keeps track of the number of sub-buffers
that were corrupted.
