In order to make the fork() magic work, Cygwin maintains its own PIDs in parallel to the actual windows PID. All the Cygwin functions that take PIDs as arguments expect Cygwin PIDs, and won't work if you give the windows PID. Example, my output of "ps -a" shows the following: PID PPID PGID WINPID TTY UID STIME COMMAND 4340 1 4340 4340 con 1003 16:13:34 /usr/bin/rxvt 3548 4340 3548 7768 0 1003 16:13:34 /usr/bin/bash 4320 1 4320 4320 ? 18 16:13:39 /usr/bin/cygrunsrv 6684 4320 6684 5772 ? 18 16:13:39 /usr/sbin/cron 5824 1 5824 5824 ? 1003 16:13:40 /usr/bin/cygrunsrv 7752 1 7752 7752 ? 18 16:13:40 /usr/bin/cygrunsrv 5116 1 5116 5116 ? 18 16:13:40 /usr/bin/cygrunsrv 6832 5116 6832 216 ? 18 16:13:40 /usr/sbin/sshd 7928 5824 7928 7212 ? 1003 16:13:40 /usr/bin/autossh 2560 7752 2560 6760 ? 18 16:13:40 /usr/sbin/cygserver 4992 7928 7928 7900 ? 1003 16:13:40 /usr/bin/ssh 6896 1 6896 6896 con 1003 16:13:50 /usr/bin/rxvt 164 6896 164 5452 1 1003 16:13:50 /usr/bin/bash 5984 3548 5984 2124 0 1003 16:13:59 /usr/bin/ssh 6628 164 6628 2432 1 1003 16:25:39 /usr/bin/ps As you can see, PID and WINPID are sometimes the same, but often not.
