 How can Icheck the pipes before reading

:       Is tehre anyway to check the pipe before actually reading
:       it? So if there is nothing on the pipe, the process will
:       not hang.

Using perl's select() is probably most probably the most portable.

There are various FIONBIO type ioctl()s you could perform as well.
