bdio file descriptor
Contains the state of the BDIO file and all data from the last header.
| unsigned char* BDIO::buf |
buffer containing the last header/record to be written
| int BDIO::bufidx |
position in buffer; a byte at position bufidx in the buffer is written to position rstart+bufstart+bufidx in the file
