The program works as >expected on Sun (after I comment out the daytime line in the file >/etc/inetd.conf) but not on the FreeBSD machine.

If you use sigaction without SA_RESTART, the signal will not restart slow system calls, causing them to flag EINTR. mkb To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
