Hi,
There is little information to go on, so I will give some broad
suggestions.
Is there only 1 SIM_SNAP.* in the directory at a time or can there be
multiple? If there is only 1, OR if you would like to get the names of all
the SIM_SNAP.XXX names, then you can use opendir/readdir to read the file
names in the directory.
If this is not an option, then how about having the terminating process
spwan the report program?
Hope this helps
