The other issue is that if you have multiple FIFOs, then the only *reliable* mechanism for making it work is to have the *reader* open non-blocking, since the opening-order in the reader doesn't necessarily correspond to the order in the writer. So you end up withThat's what it should do.But in practice, I've seen some blocks locking if their writes were blocked. That's why I suggested starting in this order.
a kind of deadlock where neither process can make any progress. -- Marcus Leech Principal Investigator Shirleys Bay Radio Astronomy Consortium http://www.sbrac.org
