Submitted-by: steve@unidata.ucar.edu (Steve Emmerson) Greetings, How would one do the equivalent of the following, BSD-ism: ioctl(fd, SIOCSPGRP, &pid); That is, in a POSIX environment, how does one set the process-group ID of processes that will receive SIGIO and SIGURG signals associated with a particular file-descriptor (which, incidentally, is a socket) to the PID of the current process. Can one use the tc*() function? Steve Emmerson steve@unidata.ucar.edu ...!ncar!unidata!steve Volume-Number: Volume 23, Number 7

POSIX.1 has no such signals SIGIO or SIGURG, nor any sockets, nor do any of the current drafts of other POSIX standards. The current POSIX.4 draft describes ways to signal asynchronous I/O completion, but the signals currently go only to the process that started the I/O. Dave Decot Volume-Number: Volume 23, Number 15
