I know that qmail does something like this with their password stuff for pop3...

How (assuming it can be done) would one going about opening a filehandle read-write in C, and then passing it along to an exec'd or system'd perl script? I believe qmail puts its authentication info on file descriptor 3, and then calls a sub process to handle the authentication. How would I do that? Can it be done? I assume qmail uses pipes, not actual files, but is there really a difference?
