Can someone from SuSE verify that on 2.4 kernels, separate pthreads of the same process will show up with ps having separate PID's? Isn't that against the standard? B-)

IIRC, that's what happens in 2.4.

Possibly. You'd have to read the POSIX 1003.1c standard to find out. The following might also be helpful. http://people.redhat.com/drepper/nptl-design.pdf -- JDL

Yes. That's also the only way to tell the threads apart so you can send signals etc.; to the outside, pthreads look the same as just another process.

I am not sure. But then, that might have been one more reason to migrate to POSIX threads with kernel 2.6. You might want to read up at http://www.kernel.org/ for more details. CU -- Stefan Hundhammer <sh@suse.de> Penguin by conviction. YaST2 Development SuSE Linux AG Nuernberg, Germany
