As David Nugent wrote: > What are the advantages (if any) of using socketpair(PF_LOCAL, ... > as compared with pipe()? socketpair() is guranteed to create a bidirectional connection. pipe() incidentally does this in 4.4BSD, and i think also in FreeBSD (which is now different from 4.4BSD since it has John D's revamped pipe code), i think also in SVR4. pipe() is way faster in FreeBSD, since it avoids the overhead from the network layers. I don't think that PF_LOCAL implements OOB data, so you don't lose anything by using pipe() except portability when it comes to a bidirectional connection. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
