I have a perl script that needs to send a few lines to a filter
process and read a few lines back.  (I have no sockets, forget that.)
I would like to do something like  pipe, fork, exec, dup2, etc...
The way I do it in "c".  But the key here is that I need to be able
to use something like dup2 to make the pipe in and pipe out handles
look like STDIN and STDOUT to the child process before I do the exec.
I would like to retain the filter aspect, reads STDIN, writes STDOUT,
of the child process.  If that were not possible, I would still need
a way to pass the file handle numbers (the fd ints, not the *FILE's).

Any Ideas?     John Watson ...!rutgers!carssdf!usenet
