optionally written. In both cases end of data is signified by
returning zero bytes for two consecutive reads.
Writing filemarks without the immediate bit set in the SCSI command block acts
as a synchronization point, i.e., all remaining data form the drive buffers is
written to tape before the command returns. This makes sure that write errors
are caught at that point, but this takes time. In some applications, several
consecutive files must be written fast. The MTWEOFI operation can be used to
write the filemarks without flushing the drive buffer. Writing filemark at
close() is always flushing the drive buffers. However, if the previous
operation is MTWEOFI, close() does not write a filemark. This can be used if
the program wants to close/open the tape device between files and wants to
skip waiting.
If rewind, offline, bsf, or seek is done and previous tape operation was
write, a filemark is written before moving tape.
