While scanning /proc may not be portable, the question asked is about checking for a running Linux process. The only way I know is scanning all directories within /proc (which as you all know are the id's of the running processes) and checking for the process file name and the process command line. If a match is found, you can assume that the process is acknowledged by the kernel as running, although the process could be a zombie process. You can then further deduce whether the latter is the case by scanning /proc/xxx/~cwd which will be unreadable (unable to be openned) if the process is a zombie process.
If someome has a better way, please tell. //------------------------------------------- On Monday 21 September 2009 14:58:20 T.
