Actually, I believe OSX (10.4.11 anyway) calls setsid() not setpgrp(). However, setsid() also causes a new process group to be created.
Using the supplied program, but running /bin/cat and then examining with 'ps ajx' I see: User PID PPID PGID SESS JOBC STAT TT TIME COMMAND derek 23944 5422 23944 15d65bc 1 S+ p1 0:00.03 ./task derek 23945 23944 23945 15d5d1c 0 Ss ?? 0:00.00 /bin/cat So the child process is in a new session, hence a new process group, and also has no controlling tty. _______________________________________________ Gnustep-dev mailing list Gnustep-dev@gnu.org http://lists.gnu.org/mailman/listinfo/gnustep-dev
