On newer linux kernels, instead of running external processes you can better read and parse /proc/pid/stat (replace pid with the PID). If you need per thread info you can read /proc/pid/task/tid/stat. These are single line pseudo files with space separated values. Much easier than parsing the free format output from ps, top, etc. http://www.kernel.org/doc/man-pages/online/pages/man5/proc.5.html Ludo _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
