Why not to use a socket (Unix socket or TCP/IP socket), push your
"0123456789" in one side and retrieve the same from the other side?
You'll need different code to open/close the socket, but writing/reading
will look the same.

Let's make a file descriptor that counts to 9.
I.e, we want to emulate the behavior:
int fd = make_counter_fd();
assert(write(fd, buf, 100) == 11);
assert(strcmp(buf, "0123456789") == 0);
Let me describe a

I'm using it as a fake "always non-blocking" file descriptor.
My main libevent-like poll loop looks like:
poll(fds)
for fd in fds:
if fd.revents | POLLIN:
fd.read_callback()
if fd.revents | POLLOUT:
fd.write_callback()
Now let's say I want a fake filed
Damn I missed that.
To my defense, this bug should be also mentioned in the POLLNVAL section.
As it stands now, it looks like the only reason for POLLNVAL is a closed
file descriptor.
Sorry and thanks.

Try to open /dev/null, and then to poll the file descriptor. Neither in the
man page nor in the standard I see anything preventing you to poll on
/dev/null, yet, it does not work on Mac OS X. You get a POLLNVAL.
