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?

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.
