'poll' and 'select' both do I/O multiplexing, but poll comes from SystemV,
and select from BSD.
IMHO, poll has more convenient argumet types than select, so I prefer to
use 'poll'.

int  poll(struct pollfd *fds, unsigned long nfds, int timeout);

struct pollfd
{
   int fd;          /* file descriptor */
   short events;    /* requested events */
   short revents;   /* returned events */
};
