Hi,
i have uploaded
http://www.gnu.org/software/xorriso/xorriso-1.3.1.tar.gz
with improved time measurement in the SCSI log.
The time measurement is now done in userspace by gettimofday()
or optional clock_gettime(CLOCK_MONOTONIC).
The shown granularity is microseconds.
Additionally there is a timestamp in []-brackets which tells
the elapsed microseconds since startup of libburn.
The timestamps can be used to determine the time between
two SCSI commands resp. ioctl(SG_IO) calls.
E.g there is a time gap of 133672-130285-1936 = 1451 microseconds
between the end of the first command and the start the next one:
PREVENT/ALLOW MEDIA REMOVAL
1e 00 00 00 00 00
6394 us [ 130285 ]
START/STOP UNIT
1b 00 00 00 03 00
1936 us [ 133672 ]
Have a nice day :)
Thomas
