Hello, I am trying to set up a unix socket such that a SIGIO signal is automatically generated when data arrives on the socket. I have tried the following: s = socket(AF_UNIX, SOCK_STREAM, 0); fcntl(s, F_SETOWN, getpid()); This, however, does not seem to work, i.e. the signal handler that I have set up does not catch the SIGIO signal. (I know that the signal handler is working properly and I know that I am getting data on the socket.) I am doing this on an Apple IIx running A/UX 1.1. Any ideas? Please e-mail to me: costello@mitre.org Thanks! /Roger
