I am trying to detect if a pipe created with socketpair() is still
active before I send a message down it. I am using
ioctl(fd, TCFLSH, 0) to accomplish this and it does not seem
to work as it gives me an error everytime (error 22)
and the pipe is active at this point.

Is there a problem using this under 2.0.33 or is there a different
way to accomplish this.

Thanks very much.

Please CC me directly.
