Hi guys, this is pretty much an old question, 'how to distinguish threads from forks from the user space?'. I understand that the only way to detect if a process is a fork or a thread is in the /proc/<pid>/stat file field 9 which corresponds to the flags of the process. However my curiosity got aroused when I installed RH8.. the system monitor gives a proper display of the process, fork and thread. I'm left to wonder how it does this. it used the 2.4.18-14 kernel. Are there any new flags that I'm missing that were introduced (by popular demand)? or does it access some kernel structure to get thid information. if yes what are the structures? tia, Sharath ===== -Sharath __________________________________________________ Do you Yahoo!?
