/autoupdate
The /autoupdate function is useful in scenarios where STREAM.EXE may need to be
recompiled, upgraded, or otherwise replaced over a network without manual
intervention at the server console. When /autoupdate is present on the command line,
STREAM.EXE
will periodically check for the presence of a file called
STREAM.EX1
in the
same directory as the executable. If STREAM.EX1 is ever found, STREAM.EXE will
terminate with exit(2), reporting the message “Server terminated due to release of new
version.”
This feature depends on the use of a batch file or script to launch STREAM.EXE . Upon
detecting exit code 2 when
STREAM.EXE
terminates, the batch file or script should
overwrite
STREAM.EXE
with a copy of
STREAM.EX1
, delete
STREAM.EX1
, and then
relaunch the new STREAM.EXE process with the same set of command-line parameters.
When any other exit code is returned by STREAM.EXE , the batch file or script can exit
normally or take other actions.
Two examples of /autoupdate batch files are included in the TimeLab directory.
SERVE.BAT is a generic launcher for STREAM.EXE that specifies the phasestation.tll and
/autoupdate options on behalf of the user, passing along any other command-line
options as well.
TSC.BAT demonstrates the use of the /format:TSC and /port:1298
options along with /autoupdate.
SERVE.BAT appears below in its entirety.
