Currect me if Im wrong but... After a fork() arent all the parent's fds shared with the children ? This means that both processes can access the same fds right ? So the epoll fd (beeing just another fd as any other) is too shared between parent and child ? Which would mean both parent and child will "control" the same epoll kernel struct when doing epoll_ctl on it ? > Ben - -- Mihai RUSU Email: dizzy@roedu.net GPG : http://dizzy.roedu.net/dizzy-gpg.txt WWW: http://dizzy.roedu.net "Linux is obsolete" -- AST -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (GNU/Linux) iD8DBQFARIVAPZzOzrZY/1QRAs+vAKCrkH/jSsJRCU6leScXz4EXC4kruQCeJfFo /remKED2xAru7uInLoyhl4o= =2cDV -----END PGP SIGNATURE----- - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
