Is there a system call named 'poll' in Digital Unix?
For example, in UnixWare 2.01 (SVR4.2) we have:
----- ["man 2 poll"] -----
poll - input/output multiplexing
int poll(struct pollfd *fds, unsigned long nfds, int timeout);
poll provides users with a mechanism for multiplexing
input/output over a set of file descriptors that reference
open files. poll identifies those files on which a user can
send or receive messages, or on which certain events have
------ [end man poll]-------
Note: we do not want to hear about 'select' call!
