Pay attention to the deadlock dangers when communicating with pipes in both directions. If both pipes block writes because they are full a deadlock is caused. It is *very* hard to avoid this in general. In some cases you can set up a protocol which uses packets up to a certain size (PIPSIZ in some implementations). Johannes Heuft unido!pcsbst!jh
