nprobe: make lockfile disable writing flows to file
|
|
Hi
We're using nprobe_6.4.3_050511_pro with a command line along the lines
of
nprobe -n none -P <outputdir> -D t -C <lockfile>
and I'd like it not to write to <outputdir> if <lockfile> exists.
I've created the following patch that seems to do the job, will it have
any nasty side effects? I'm worried about skipping the free() calls
toward the end of exportBucket(), but my C isn't good enough to tell if
this will be a problem.
